Putting a £1,000 Macbook Air in the oven might not be the first port of call after your trusty laptop fails to power on; I however, was feeling lucky that day. TL;DR: Cranking the temperature up higher than the recipe suggests is a bad idea, unless your goal is to simultaneously desolder most components from the motherboard. Here’s a timeline of events:
Day 1: The MacBook’s sudden coma
This is the MacBook Air, bought in 2014 and specced up with maximum RAM and the fastest CPU (see FAQ at end for details). I’d expected to eek many years out of it; little did I know it would soon be entering a sauna of silicon destruction.
MacBook Air running fine before it brokeMacBook Air before (only picture I had, sorry)
It was time to pack up the MacBook after a loyal day of service. When returning the laptop to its soft case, I misjudged the approach and my trusty machine dropped 30cm or so to the floor, landing on its corner. I thought nothing of this originally; it wasn’t first time the MacBook had been dropped and it usually coped perfectly fine. However, when opening the lid to check I hadn’t broken the screen, the tiny CPU fan screamed up to full speed, accompanied by a flash of the keyboard and screen backlight. Then all went black, the MacBook was limp and unresponsive.
Day 2: Administering first aid
Not a problem I thought, dropping it on the corner like that might have shaken a few bytes of SDRAM around, but nothing a power reset wouldn’t fix. However, whilst holding the power button down for increasingly desperate lengths of time, my optimism dropped until the point of acceptance that it just wasn’t going to switch on.
Following tech support guidance from the internet, all the following were given a shot:
* Performing multiple NVRAM/PRAM and SMC resets. * Leaving the battery disconnected overnight. * Disconnecting all components/connectors from the logic board, then reassembling. * Bridging the logic board “power on pads”, optimistically hoping for a broken power button. * Trying multiple power supplies. * Applying a little percussive maintenance.
Nothing worked, the MacBook remained lifeless. It wouldn’t even take a charge, the light on the charger refused to illuminate at all.
Day 2: Bake day
The internet has happy tales of other owners reviving their dead MacBooks by gently baking them in the oven. I figured, if it’s good enough for those four people on the internet - it’s good enough for me. The idea is to heat the logic board just enough to reflow solder any broken connections.
Only the logic board should go in the oven, so the first stage is to remove all components and connections from the board. Despite the MacBook Air’s tiny form factor, this was surprisingly simple, although it does require use of a pentalobe and Torx driver bit. The I/O board was also removed from the chassis, as my suspicion was that the offending component would likely by located on that board - plus it would give the logic board a companion during the bake-off.
Recipes suggest baking at 170 °C for 7 minutes. The instructions are not specific about whether this is for fan ovens, whether preheating is required or whether an egg-wash should be applied beforehand. In my mind, thermal shock is also a greater concern when baking a motherboard compared to a Victoria sponge, so I opted to bake from cold. Weighing up the consequences of covering our main oven in molten MacBook, I also chose to use our standalone oven (purchased solely for extra Christmas dinner capacity) instead of our kitchen oven. There’s also the matter of fire safety, which I mitigated by placing the standalone oven within booting distance of the outside door.
Arranging the logic and I/O boards on the middle oven rack, I cranked up the dial to 170 °C and nervously waited for the oven to reach temperature. Unsurprisingly, gently baked MacBook doesn’t smell particularly delicious, but thankfully I’d prepared for this in advance by placing the oven in an isolated room with a door to the outside kept wide open. Six minutes into the bake, everything was still looking cushty. A few small wires had started going a bit gooey, but I was positive that the boards would survive.

With confidence high and the bake nearly finished, for the final 60 seconds I thought I’d go off-piste and crank up the temperature to 180 °C - I wanted to make sure things were cooked through. Curiously peering through the oven window, all hell broke loose within 30 seconds: The room filled with sounds of popcorn being made as resistors and components desoldered themselves from the logic board and dropped onto the oven floor. The previously clear air was replaced with an acrid haze. Then the bake reached it’s finale as the logic board bowed up in the middle, accompanied by the screeching sound of the CPU being wrenched off its socket. I lunged for the power switch and yanked open the oven door, hoping to limit damage. Then, as quickly as the bowing started, everything calmed down and the board returned to its original shape. With the board still hot, a wooden spoon was employed to desperately poke the CPU back onto its mount - with little success.

With the acrid air clearing and the oven gently ticking as it cooled, I began re-assessing the decision to place a £1,000 MacBook in the oven. Hoping to salvage some functionality, I heated a soldering iron and spent 30 minutes with a tweezer, unsuccessfully trying to solder the miniature components back onto the logic board. After the third ‘ouch’, I called time; there was no hope left.

Even before I stuck the MacBook in the oven, it was already out of warranty. I know other owners that have paid many hundreds to have Apple replace the logic board. In my case I couldn’t even be sure that the logic board was the only broken component so didn’t want to start that cash sink.
Although I am tempted to take it to the genius bar now, just for entertainment.
What MacBook Air model was this?
Purchased in September 2014 with:
* 1.7 GHz Dual-Core Intel Core i7, Turbo Boost up to 3.3 GHz. * 8 GiB 1600 MHz LPDDR3 SDRAM. * 128 GB PCIe-based Flash Storage.
Why not use a thermometer?
Pure laziness. I own numerous digital oven thermometers and infrared thermometers that would have been up to the job. The entire bake was performed in a rushed 60 minutes after work one weekday. In hindsight, if I’d have spent half as much time as I spent preparing this article on proper temperature control, I probably wouldn’t be sitting here with a bunch of useless spare parts.
Have you replaced it with another MacBook?
Not yet - I purchased a cheap tower PC instead. It had been over 10 years since I moved to laptops only and I wanted to see what had changed since. Turns out a lot has changed and this new machine has quickly become one of my favourites! Specs:
* AMD Ryzen 3 2200G CPU (/APU) with Radeon Vega 8 Graphics - considering the cost is exceptionally low, the performance of this unit really impresses. * 8 GiB DDR4 RAM - already nudging up on this limit regularly, so will likely upgrade to 16 GiB. * 120 GB SSD - used for boot and root filesystem, encrypted with LUKS. * 1 TB spinning rust HDD - used for bulk files, encrypted with LUKS. * Standard Ubuntu (not very exciting I know). In the beginning, kernel support for this line of APU was poor, there was a seemingly 50/50 chance that it would boot successfully and it would often lockup randomly. However, since 4.18.0 everything seem to work well!
While on the road (well, train) I now sport a bright purple HP Stream 11-r001na, which my colleagues have branded the “Fisher-Price” laptop. Trying to get Ubuntu 18.10/GNOME 3.30 working within it’s 2 GiB RAM (whilst leaving room for anything else) was too much of a challenge, so I’ve switched to Lubuntu and LXDE/LXQT, which has made this mini-machine just about usable. The specs, for entertainment:
* Intel Celeron N3050 1.6 GHz * 2 GiB DDR3L SDRAM * 32 GB eMMC
What on earth is that oven?
It’s a Klarstein MasterChef 60 Mini Oven (not that 60 L is very mini), which as mentioned above is owned solely for extra Christmas dinner capacity. It does have a small convection fan, but the heat sources are from four unshielded elements: two at the top and two at the bottom. Not the most ideal oven for even heat distribution, but certainly a safer choice than using a built in kitchen oven as it allowed the acrid fumes to be kept outside. It was also a safer choice for myself, as a I fear there would have been some disapproval if I’d have managed to fuse a circuit board to the inside of our kitchen oven.

Have you ever been interested in monitoring the air quality in your home or outside where you live and work? This project, which we’ve dubbed balenaSense, will get you up and running with a setup to take readings of temperature, humidity, barometric pressure, and air quality, and provide a dashboard that you can access from anywhere to see the stats at a glance and monitor trends.
Table of contents
Building an air quality & weather station used to involve a lot of wiring and different sensors, but with the advent of sensors that combine all the readings into one component on a nice little breakout board, it’s easy to get started.
We’re going to look at monitoring temperature, humidity, barometric pressure and air quality using an all-in-one sensor that connects directly to a Raspberry Pi with no additional components required. You don’t need any experience in electronics but a soldering iron would be handy (although not required). This project implements a database to store historic readings along with a graphical interface to see current readings and trends at a glance.
Here’s the shopping list for this project. Depending if you’d like to crack out the soldering iron or not will dictate what sensor board you can use; some are plug and play, some require a little soldering.
I donʼt want to solder
If you donʼt want to solder, youʼll need:
I want to solder - let me at it!
If youʼre happy doing a little soldering, youʼll need:
If you already have one, this project also supports the use of the Sense HAT, with the added bonus that youʼll get a smiley face showing on the LED matrix (depending on the air quality, of course)!
You can get hold of the Bosch BME680 sensor on a breakout board from a variety of vendors too, all at varying costs.
Note: The Pimoroni breakout board is the one we’ve used in this article; this board has the added benefit that the pins are broken out in the correct order to just plug straight into the Raspberry Pi GPIO header. When using other boards you’ll need to be careful to ensure the pins for power, ground and the I2C bus (SDA and SCL) are matched - this is explained further on in the guide.
We’ve set up the balena-sense project on GitHub which contains all of the software, configuration and code you’ll need to start taking readings straight away. We’re going to deploy this project on balenaCloud using a free account to push the project and all the software to your Raspberry Pi as well as to provide remote access. Therefore, you’ll need:
Putting the hardware together
You’ve got very little to do on the hardware front for this project; our goal here is to connect the sensor board you purchased to the Raspberry Pi general purpose input/output (GPIO) header.
The BME680 sensor communicates with the Raspberry Pi over a bus called I2C (eye-squared-see), which is a serial communication bus that requires 2 wires. These two communication wires are referred to as serial clock (SCK) and serial data (SDA). In addition to the two communication wires, we also need to provide the sensor with power (3.3V, or 3V3) and ground.
If you went for the solder-free option from Pimoroni or Sparkfun, or are using the Sense HAT, you’ll just have to plug your shiny new components together along with your Raspberry Pi, and all of the connections will be made for you - go forth, to the next step!
If you decided to connect a sensor directly to your Raspberry Pi, either the Pimoroni one or any one of the other breakout boards from one of the other suppliers, the main things to watch out for are that the pins described above (SDA, SCK, 3V3 and GND) are correctly connected.
A useful site for working with the GPIO header on your Raspberry Pi is pinout.xyz; it clearly shows us that the pins we need are 1 (3V3 power), 3 (SDA), 5 (SCL), and 9 (Ground). The 40 pin GPIO header is standard across the Pi 2 and later. You’ll notice that if you’re using the Pimoroni board and solder on the included header, the pins are in exactly the right order to connect the boards together. Notice how the writing on the board matches the pins in the pinout diagram above.
However, if you connect the sensor like this you may find the readings are affected by the heat from the Raspberry Pi CPU; more accurate readings can be taken by extending the sensor away from the board, which can be achieved using male-to-female Dupont cables (or Jumper Jerky), as below:
Similarly, if you’re using one of the other sensors where the pinout diagrams do not match exactly, you can connect these boards to your Pi using the same method, ensuring that you match up 3V3, SDA, SCL, and GND. Your board may also have pins for SDI, SDO, CS - you can ignore these and leave them unconnected as they’re used for an alternative serial peripheral interface (SPI) to the sensor which we’re not using in this project.
In the photos above we’re using a Raspberry Pi 3A+, but you can use a Pi Zero as pictured at the start of the guide for a lower cost solution.
Setting up the Raspberry Pi
We’re going to flash an SD card with balenaOS via a download from the balenaCloud dashboard and add the device in order to push the project, and set things up in such a way it can easily be updated later.
The first thing to do is to get set up with a balenaCloud account; this means signing up if you haven’t already, adding an application and adding a device.
Step 1 - Sign up to balenaCloud
The first thing you’ll need to do is sign up for an account. If you’ve already got a GitHub or Google account you can use that to login and bypass the signup process.
Sign up here
Step 2 - Create an application
Add an application selecting the correct device type for the device you’re using, and choosing Starter as the application type, then hit Create New Application. Using the starter application will provide you with all of the features of the microservices application and is free up to and including your tenth device.
This will take you to the dashboard for your newly created application, where you can move on to the next step and add your device. The name you give your application is up to you, but youʼll need it later on in the guide when you push your code.
Step 3 - Add a device and download the OS
Once your application has been created, you can setup and add a device within that application by clicking the green ʼadd deviceʼ button. When you add a device you specify your device type, which is important that it matches the device you’re using, and if you are connecting to a wireless network you can set your WiFI SSID and passphrase here too.
This process creates a customized image configured for your application and device type and includes your network settings if you specified them.
Note: When youʼre first getting started, a development image will be most useful, as it permits a number of testing and troubleshooting features. More details on the differences between development and production images can be found here. If youʼre confident you can go ahead and deploy the production image straight away -- thatʼs what Iʼm running.
Step 4 - Flash your SD card and boot the device
Once the OS image has been downloaded, it’s time to flash your SD card. You can use balenaEtcher for this.
Once the flashing process has completed, insert your SD card into the Raspberry Pi and connect the power supply.
When the device boots for the first time, it connects to the balenaCloud dashboard, after which you’ll be able to see it listed as online and move onto the next step.
Troubleshooting: It should only take a few minutes for the new device to appear in your dashboard, If your device still hasnʼt shown up on your dashboard after a few minutes, something has gone wrong. Thereʼs an extensive troubleshooting guide in the documentation, with lots of information on why this could be, but if you still canʼt get your device online, come on over to the forums where we’ll be able to help out.
Deploying the software
Now that your Raspberry Pi has been provisioned, has booted, and connected to balenaCloud, youʼre ready to push the application code to the device.
Installing the balena CLI tools
If you already have (or can setup) npm on your machine, this is most likely the easiest way to get the CLI tools up and running quickly. However, there are also standalone binaries for Windows, macOS and Linux available. Note: if youʼve already installed these tools to complete another of our projects, you donʼt need to do this part again - skip directly to the next step.
The documentation for the CLI tools is the best place to start and covers the installation and setup of both the npm package and the standalone binaries.
When you have the CLI installed and working, the first step is to login to balenaCloud by issuing the balena login command:
Once you’ve reached this point, and have a working CLI which has been logged in to your account, youʼre ready to start pushing code to your Raspberry Pi.
Downloading the project from GitHub
The next step is to download the code for this project from GitHub. Go to: https://github.com/balena-io-projects/balena-sense/ and download the project.
The blue button will download a .zip file of the project which youʼll need to unzip, but if youʼre already familiar with Git you can use git clone in the normal way.
Pushing the project code to your Raspberry Pi
As you have the CLI setup and the latest code downloaded, you can now execute a single command to push that code to balenaCloud which in turn builds the Docker image and handles the process of setting it up and running it on your device.
From within the unzipped project directory, execute balena push , where appName is the application name you set back at the beginning of the guide. For example: balena push balenaSense.
If everything worked out correctly, after a few minutes your device information screen in the dashboard should look something like this, showing the services running, one for each of the software components.
When you push the code for the first time it can take a few minutes to download (dependant on your internet connection speed) but after that, only the changes in the container are downloaded so things happen much quicker.
Note: that when the application first starts (and youʼre using the BME680 rather than the Sense HAT) the sensor performs a ‘burn-in’ over a 5-minute period. Readings will not be taken and readings not inserted into the database during this period. The application will log a countdown, which you can see within the balenaCloud dashboard as per the below screenshot:
After the countdown has reached zero, you’ll see a message that says ‘Starting loop…` and readings will now be taken and inserted into the database every 10 seconds.
Viewing the dashboard
Hopefully you got your device flashed, connected to your network and up and running without too much trouble. One of the great benefits of using a free balenaCloud account is that you’re able to use the Public Device URL feature.
Enable this toggle on your device and click the blue arrow to access the dashboard; you can share this link or bookmark it for use from your phone or another mobile device. As long as your balenaSense device is online and working, you’ll be able to access your dashboard from anywhere!
If you don’t want to enable the public device access, you can still view the dashboard from within your own local network by using the IP address value from the image above. Yours will be different, but if you enter http:// into a browser, you’ll still be able to access the dashboard as long as you’re on the same network as the device. For example, to access my device I would use http://10.1.231.36.
If youʼd like to log in to Grafana and start playing with the settings, the default credentials are admin and admin.
How does it work?
This project has 3 main components, which are separated into 3 services. These are the names of the services you’ll see on your balenaCloud dashboard:
* InfluxDB - A database, used for storing sensor readings * Sensor - The Python library and code for accessing the sensor, taking readings and saving them in the database * Grafana - Used for creating a dashboard with graphs & reports
The BME680 sensor from Bosch gives us readings for temperature, humidity, pressure and a gas content reading provided in terms of resistance. The sensors for temperature, humidity, and pressure give us useful readings out of the box, but the gas resistance reading on its own is not a lot of use. It gives us an indication of the change in compounds in the air, so when the sensor application starts, it sets a baseline and monitors change. The indicative air quality reading is given in percentage and takes into account the effect of humidity and gas reading.
If youʼre using the Sense HAT, which doesnʼt have a gas sensor, weʼve approximated the air quality reading using target values for temperature and humidity.
So by now hopefully you’ve got the project fully up and running, have accessed the dashboard and have been taking readings and filling up your database. Here are a few more things to take a look at before you move on to the next project.
Change the password
If you’re leaving your device publically accessible, it’s a good idea to change the password for Grafana.
We’ve set the system up with a default username and password of admin and admin. You can change this by logging into Grafana using the button in the lower left corner of the dashboard; you’ll be prompted to change it upon first login.
The dashboard & reporting software we’re using, Grafana, has a lot of configuration options and settings for you to play with. We’ve set up a basic dashboard that gives you a gauge and a graph for each of the 4 readings that we’re taking.
You can customize each panel on Grafana after you’ve logged in by hovering over the title and going to edit. I recommend having a play with the options - the changes to your dashboard are not saved automatically so if you make a mistake you can reload the page and everything will revert to how it was. If you make some changes you want to keep, hit save at the top of the dashboard and all of your settings will be saved to your device.
You can customize the gauges too; for example on the pressure gauge, we’ve set up some basic bands and text values to replace the numbers. You’re free to edit all these to whatever works for you!
Build a housing
Sensors like this ideally like to be housed in a radiation shield (sometimes called a Stevenson Screen), to prevent sunlight and radiated heat affecting the readings. If you’re monitoring the environment indoors, it isn’t quite so critical, but if you’re monitoring outdoors, positioning and protecting the sensor is important to get accurate readings.
Commercial radiation shields are available, such as this one from Davis, but can be quite expensive, so there are DIY options around too.
There are a few different options for BME680 housings and Stevenson screens on Thingiverse; take a look and see if any of the designs will work for your application.
Thanks for reading! If you decided to build your own air quality monitor, we’d love to hear how it went, similarly if you got stuck, have any questions or just have some suggestions for future development of the project, let us know in our forums at https://forums.balena.io, on Twitter @balena_io, on Instagram @balena_io or on Facebook.

#HackerNews #air #cockpit #depicts #fix #for #frantic #jet #lion #pilots #recorder #search #voice
JAKARTA/SINGAPORE/PARIS (Reuters) - The pilots of a doomed Lion Air Boeing 737 MAX scoured a handbook as they struggled to understand why the jet was lurching downwards, but ran out of time before it hit the water, three people with knowledge of the cockpit voice recorder contents said.
The investigation into the crash, which killed all 189 people on board in October, has taken on new relevance as the U.S. Federal Aviation Administration (FAA) and other regulators grounded the model last week after a second deadly accident in Ethiopia.
Investigators examining the Indonesian crash are considering how a computer ordered the plane to dive in response to data from a faulty sensor and whether the pilots had enough training to respond appropriately to the emergency, among other factors.
It is the first time the voice recorder contents from the Lion Air flight have been made public. The three sources discussed them on condition of anonymity.
Reuters did not have access to the recording or transcript.
A Lion Air spokesman said all data and information had been given to investigators and declined to comment further.
The captain was at the controls of Lion Air flight JT610 when the nearly new jet took off from Jakarta, and the first officer was handling the radio, according to a preliminary report issued in November.
Just two minutes into the flight, the first officer reported a “flight control problem” to air traffic control and said the pilots intended to maintain an altitude of 5,000 feet, the November report said.
The first officer did not specify the problem, but one source said airspeed was mentioned on the cockpit voice recording, and a second source said an indicator showed a problem on the captain’s display but not the first officer’s.
The captain asked the first officer to check the quick reference handbook, which contains checklists for abnormal events, the first source said.
For the next nine minutes, the jet warned pilots it was in a stall and pushed the nose down in response, the report showed. A stall is when the airflow over a plane’s wings is too weak to generate lift and keep it flying.
The captain fought to climb, but the computer, still incorrectly sensing a stall, continued to push the nose down using the plane’s trim system. Normally, trim adjusts an aircraft’s control surfaces to ensure it flies straight and level.
“They didn’t seem to know the trim was moving down,” the third source said. “They thought only about airspeed and altitude. That was the only thing they talked about.”
Boeing Co declined to comment on Wednesday because the investigation was ongoing.

The manufacturer has said there is a documented procedure to handle the situation. A different crew on the same plane the evening before encountered the same problem but solved it after running through three checklists, according to the November report.
But they did not pass on all of the information about the problems they encountered to the next crew, the report said.
The pilots of JT610 remained calm for most of the flight, the three sources said. Near the end, the captain asked the first officer to fly while he checked the manual for a solution.
About one minute before the plane disappeared from radar, the captain asked air traffic control to clear other traffic below 3,000 feet and requested an altitude of “five thou”, or 5,000 feet, which was approved, the preliminary report said.
As the 31-year-old captain tried in vain to find the right procedure in the handbook, the 41-year-old first officer was unable to control the plane, two of the sources said.
The flight data recorder shows the final control column inputs from the first officer were weaker than the ones made earlier by the captain.
“It is like a test where there are 100 questions and when the time is up you have only answered 75,” the third source said. “So you panic. It is a time-out condition.”
The Indian-born captain was silent at the end, all three sources said, while the Indonesian first officer said “Allahu Akbar”, or “God is greatest”, a common Arabic phrase in the majority-Muslim country that can be used to express excitement, shock, praise or distress.
Indonesia plane crashA Lion Air flight with 189 people on board crashed into the sea shortly after taking off from the Indonesian capital, Jakarta.
The plane then hit the water, killing all 189 people on board.
French air accident investigation agency BEA said on Tuesday the flight data recorder in the Ethiopian crash that killed 157 people showed “clear similarities” to the Lion Air disaster. Since the Lion Air crash, Boeing has been pursuing a software upgrade to change how much authority is given to the Maneuvering Characteristics Augmentation System, or MCAS, a new anti-stall system developed for the 737 MAX.
The cause of the Lion Air crash has not been determined, but the preliminary report mentioned the Boeing system, a faulty, recently replaced sensor and the airline’s maintenance and training.
On the same aircraft the evening before the crash, a captain at Lion Air’s full-service sister carrier, Batik Air, was riding along in the cockpit and solved the similar flight control problems, two of the sources said. His presence on that flight, first reported by Bloomberg, was not disclosed in the preliminary report.
The report also did not include data from the cockpit voice recorder, which was not recovered from the ocean floor until January.

Soerjanto Tjahjono, head of Indonesian investigation agency KNKT, said last week the report could be released in July or August as authorities attempted to speed up the inquiry in the wake of the Ethiopian crash.
On Wednesday, he declined to comment on the cockpit voice recorder contents, saying they had not been made public.

#HackerNews #air #decline #first-class #travel
DUBAI IS OFTEN called a “Disneyland for the rich”. At the city’s airport the three first-class lounges of Emirates, the United Arab Emirates’ flag-carrier, do not disappoint. Each one is as big as the terminal’s concourse, built to accommodate thousands of passengers. But every day only a hundred or so enter each first-class lounge. Instead of the overpriced fast-food on offer in the public concourse, a maze of restaurants and bars serve free caviar and champagne. In their duty-free sections no knock-off cigarettes or booze are in sight. Think instead Bulgari necklaces and whisky at $25,000 a bottle. The facility is so large, its manager admits, that the most common reaction heard from new arrivals is, “Oh my God, where is the lounge?”
Yet the rows of hundreds of empty armchairs suggest that something is not quite right. Airlines are falling out of love with first class. And that is true even of Emirates, which sells far more first-class tickets than any other carrier (see chart 1). The time to launch new first-class offerings is at ITB Berlin, the world’s largest trade show for the travel industry, which opened on March 6th. At this event in 2017 Emirates unveiled a new onboard bar and lounge for its highest-paying passengers. The same year its big rival in the Gulf, Qatar Airways, launched the world’s first skyborne double-beds. But the mood has changed. Last year Emirates stopped attending the show at all.

The decline of first-class air travel seems at first glance surprising. Facilities onboard have never been so good. On its A380 superjumbos, Emirates first class provides in-flight showers. Moreover, the number of very rich people has risen sharply. Forbes, a magazine, estimates that the stock of billionaires has doubled to more than 2,100 over the past two decades. And the rest of the luxury-travel business is booming. Richard Clarke of Bernstein, a research firm, estimates that the number of luxury hotels in Asia could increase by as much as 168% over the next decade.
Even so, many analysts predict that first class will soon disappear. In America it is already almost extinct. Ten or so years ago almost all the many hundreds of long-haul aircraft based there offered first-class seating; now only about 20 do. Elsewhere in the world an increasing number of airlines, including Turkish Airlines and Air New Zealand, have already scrapped it completely. On the majority of the most-travelled long-haul routes the number of first-class seats available has fallen sharply in the past decade (see chart 2). Even the airlines that sell the most first-class fares are curbing their enthusiasm. The number of first-class seats has been slashed from 14 to 11 on Emirates’ superjumbos and from 12 to six on those flown by Singapore Airlines.
When commercial aviation got going after the second world war there was only one class: first. Economy appeared in the 1950s. It was followed in the 1970s by business class and in the 1990s by premium economy, to fill the gap between business and cattle class.
Despite the proliferation of cheaper seats, airlines still make a lot of their money from the more expensive ones. Emirates claims that first- and business-class passengers are 12% of the total but generate about 40% of its turnover. High demand for flat beds on transatlantic flights is what has saved European flag-carriers such as British Airways (BA), Air France and Lufthansa from going out of business. Ross Harvey of Davy, a stockbroker, points out that transatlantic low-cost airlines that have tried to offer just economy or premium-economy seats, such as Norwegian and WOW, have struggled to make money.
Airline bosses are acutely worried about the decline in demand for first class. But they have themselves partly to blame. The industry has disrupted itself, points out Geoffrey Weston of Bain & Company, a consultancy. On short-haul flights, the low-cost model has won. Most “first-class” passengers on these routes now sit in seats with the same legroom as economy passengers, albeit with an empty middle seat, and make do with extras such as lounge access, and food and drink.
On longer routes, new seats that turned into fully flat beds were a game-changer. These were originally introduced by BA in first class in 1995, and much sought after. If travellers can sleep comfortably in the sky, they can save the cost of a hotel or, more importantly for time-pressed corporate warriors, a day’s working time. However, in 2000BA launched a similar seat in business, and most carriers have followed suit. That has weakened the case for flying first class. Most companies think a flat bed in business class is good enough for their employees. Only a few honchos are allowed to enjoy first class on the company dime, says Greeley Koch of the Association of Corporate Travel Executives, a trade group.
Changing attitudes among the very rich are also sapping demand. Over the past decade the number of billionaires has grown fastest in China, India and the tech hubs of America. But many self-made tycoons want their children to have the “normal” middle-class upbringings they themselves had, says Charlotte Vangsgaard of ReD Associates, a consultancy. So they book themselves and their families into business, or sometimes economy, rather than first.
Airlines that offer first class say they still do so for two main reasons. The first is to use upgrades from business class as an incentive for loyalty from both corporate and individual customers. But as the gap between business and first has narrowed, frequent flyers have begun to respond better to other incentives, such as access to lounges or to special hotlines.
The second reason for maintaining first class is also weakening. That is what Samuel Engel of ICF, another consultancy, calls the “halo effect” an airline creates by advertising first-class facilities. In other words, flyers begin to think economy on Emirates, say, is fancier than on other airlines by association with features in its first class, such as in-flight showers. This can be an effective marketing tool. For instance, Etihad, a rival to Emirates in the Gulf, has probably had more press coverage for its onboard first-class apartments called “The Residence”, of which it has only ten, than all its 30,000 other seats combined.
Many airlines, however, are no longer convinced by this argument and have slimmed down their first-class offerings. One such is Air France-KLM, whose chief executive in 2014, Alexandre de Juniac, claimed that first class was “little more than a costly marketing gimmick” and that “no one makes money out of it”.
Yet some still do, particularly Emirates. One advantage it has is that it can combine traffic from various destinations using its hub in Dubai. This helps it make first class viable on routes where it might otherwise struggle to attract first-class passengers. As a result, over 90% of its first-class bookings are paid for, rather than free upgrades.
Why do some passengers still want to fly first rather than business? Privacy is one reason, says Sir Tim Clark, the airline’s president. Smaller cabins and walled-off seats make it easier for a celebrity to fly unnoticed by fellow passengers who might otherwise tweet unflattering pictures of them drooling in their sleep. Another is flexibility. First-class passengers want to sleep and eat when they choose, not on a timetable set by cabin crew, as often happens in business class, says Joost Heymeijer, head of Emirates Inflight Catering.
But even Emirates’ first- and business-class sales are threatened by private jets. These let executives avoid the wait for a scheduled flight. It is also much quicker to pass through security in a private-jet terminal than an airport. And in America ten times as many airports are open to private jets as are available for the bigger aircraft airlines use. Moreover, executive jets are becoming cheaper in relative terms, says Adam Twidell of PrivateFly, a private-jet booking service. New shared-ownership and ride-hailing services allow the cost of a private jet to be spread over many users.
The rise of the private jet may be good news for bigwigs rushing to meetings. But it is bad news for the environment. The World Bank estimates that first- and business-class passengers on a narrow-body jet already generate between 2.5 and six times more carbon emissions per person than the poor saps crammed into the cheap seats. Private jets, obviously, are worse. A half-filled private jet is roughly five times dirtier than business class and 12 times dirtier than economy on short-haul routes.
A new breed of supersonic executive jets will be even more polluting. The International Council on Clean Transportation, a think-tank, estimates that their emissions will be five to seven times greater than for standard jets. Boom, one of the startups hoping to produce these jets, has forecast that up to 2,000 such supersonic aircraft will be built by 2035.
Another trend that could hasten the end of the arms race in first-class facilities is the shift towards smaller passenger jets. On February 14th Airbus, maker of the A380 superjumbo, announced that it will stop production of new ones from 2021. This aircraft’s bulbous fuselage left space that could be devoted to fancy first-class features such as Emirates’ showers and Etihad’s apartment suites. The smaller and more efficient jets that have consigned the A380 to an early grave lack this extra space. It would be hard to fit showers, for instance, in the new long-haul narrow-body jets now available.
So Emirates will need another way to get its passengers to pay extra—perhaps by further upgrading those cavernous lounges. Its lounge manager in Dubai sounds perplexed: “You need to do something different to make first class worth it.”

#HackerNews #agents #air #canada #overselling #practices #reveal
A pair of Air Canada insiders are shedding light on the airlineʼs policy of overselling flights, revealing what they say is a widespread practice of duping passengers into believing they have a seat on a plane and stringing them along until the last possible moment.
As a way to try to maximize revenues, airlines are allowed to sell more plane tickets for a flight than there are available seats, but the former and current ticket agents who spoke with Go Public say Air Canada is less than transparent with customers who are likely to be denied boarding because a flight has been oversold.
"Itʼs never fun to have to lie to people," said the former customer sales and service agent, who worked at Air Canadaʼs check-in counter at Vancouver International Airport for several months before quitting just over a year ago.
"I had to tell people over and over again that they were gonna get on the plane, when I knew that they might not."
* Are you an airline industry insider? Contact Erica and the Go Public team
The other insider, a longtime Air Canada ticket agent who still works for the airline and trains employees, says he is now one of the people teaching new agents to not be forthcoming.
"I say to the new hired agents, ʼYou canʼt put up with confrontation all day long. If someone has ʼGTEʼ [for "gate"] on their boarding pass, it means they donʼt have a seat. But if you explain that to them, theyʼll get upset. So just send them to the gate,ʼ" he told Go Public.
"I train people to dupe passengers."
The day he spoke with Go Public, he said heʼd pointed dozens of Air Canada customers to a gate knowing they didnʼt have a seat.
CBC has agreed not to identify the current and former Air Canada employees because doing so could jeopardize their current employment.
Air Canada says the practice of overselling is carefully managed, and employees are trained to be transparent with customers.
ʼEvery route could be oversoldʼ
The former Air Canada agent said he contacted Go Public because he wanted travellers to know how often staff are forced to scramble to find seats for passengers stuck on oversold flights.
"I was shocked," he said. "I had no idea that Air Canada was doing this at this scale."
I told them they had nothing to be worried about, and it absolutely killed me.- Former Air Canada ticket agent
It didnʼt matter if passengers were flying within Canada, to the U.S. or overseas, he said.
"Every route could be oversold."
ʼIt absolutely killed meʼ
The former agent says he quit because he couldnʼt take the stress of constantly misleading customers.
As an example, he tells the story of an excited family flying together for the first time. When they checked in, their boarding passes didnʼt have assigned seats.
"I just felt awful about it, but I had to say that they were going to have a great trip, and push them through [to the gate]," he said.
"They ended up not getting on. I tracked them, and they were bumped. It was the last flight out that day."

He remembers a couple on their way to a honeymoon in Hawaii, who didnʼt have confirmed seats on an oversold flight.
"I told them they had nothing to be worried about, and it absolutely killed me," he said. "The chances of them making it on [the flight] were slim to none."
In another case, a passenger who was on his way to have life-changing surgery in Alberta the next day stood a good chance of getting bumped from a flight, he said.
"I had to do a complimentary upgrade to make it happen — which is something that I shouldnʼt have done. But at the end of the day, he needed to get on that plane."
Your seat ʼwill be assigned at the gateʼ
The former agent says he was told during training not to inform customers at the check-in counter that the reason they donʼt have an assigned seat is because the flight was oversold.
"Nobody wants panic from the second of check-in. Thatʼs not fun for the company to have to deal with," he said.
"I really wasnʼt able to tell people exactly what was going on and give them the full picture. They were strict about that. Weʼre trained to tell them that … they have nothing to worry about."
He says he also felt badly for colleagues working at the gates, who had to deal with passengers once they learned the flight was oversold and they didnʼt have a seat.
Air Canada responds
Go Public requested an interview with Air Canada, but the airline declined.
In an email, spokesperson Angela Mah disagreed with many of the allegations made by the current and former Air Canada employees, and dismissed the impact of overselling.
"Overselling ... accounts for less than 1 per cent of passengers booked," wrote Mah, explaining that the airline flew approximately 51 million customers in 2017/18.
Air Canada says overselling ʼbenefits customers by keeping fares lowerʼ and allows the airline to operate less-travelled routes. (Pat Fogg/CBC)
That one per cent amounts to 510,000 tickets oversold, but Mah says only a fraction of that number results in customers being denied boarding because "several million customers per year no-show."
* Read Air Canadaʼs full response to CBC Go Publicʼs questions
Mah pointed out that overselling is approved by the Canadian Transportation Agency and is a "common practice amongst many international network airlines to ensure the maximum number of seats are filled on a departing flight."
Overselling "benefits customers by keeping fares lower" and allows the airline to operate less-travelled routes, Mah said.
She also said the bigger reason passengers end up with no seat on a plane is due to "overbooking" — when an aircraft is replaced with a smaller plane, for a host of potential reasons including mechanical issues.
She would not confirm how often this happens, saying those numbers are "commercially sensitive" and an unavoidable reality for all airlines — including Air Canadaʼs competitor, WestJet.
WestJet told Go Public it does not "intentionally oversell" seats.
Internal documents obtained
Internal documents on Air Canadaʼs employee website explain that the airline oversells flights because its management team "is tasked with ensuring that the maximum revenue potential is made on each and every flight."
In 2017, Air Canada reported a profit of $2.04 billion, more than double what it earned the previous year. Figures for 2018 will be released shortly.
The website says the airline "uses a sophisticated system" to "calculate the acceptable level of oversell risk."
It then explains what Air Canada agents should do in the event there are more passengers than seats for a flight.
A screenshot of an internal Air Canada website. It instructs agents to ʼmake the compensation sound as attractive as possibleʼ when trying to entice passengers to give up their seats on oversold flights.
"When flights are oversold there is certainly a level of stress for both the gate agent and customers involved," the website says.
"Soliciting volunteers to travel on later flights not only fulfills our legal requirements, but may also assist the gate agent in alleviating some of that stress. Making announcements for seeking volunteers [to give up their seats] makes a positive impression on our customers, by demonstrating that we are trying our best to accommodate all of our customers."
The Air Canada agent who works in a busy airport says accommodating customers can sometimes be extremely difficult.
"Itʼs hell for us to have to turn these passengers away," he said.
"Kids are crying. Saying, ʼDaddy, you promised weʼd be [there]for dinnerʼ and I have to explain that the flight is oversold."
Business passengers are ʼmost valuableʼ
Fred Lazar, an airline industry analyst and associate professor of economics at York Universityʼs Schulich School of Business, says one reason passengers might get bumped from a flight is because Air Canada has focused on servicing the countryʼs business sector — frequent flyers who want an international network of flight options and often pay premium fares for the flexibility of changing their flights last minute.
"Top-tier passengers are the most valuable," Lazar said.
"So [the airline] will bend over backwards to accommodate them, even if it means bumping some basic economy passengers from the airline and enduring the bad publicity for a short time."
Airline industry analyst Fred Lazar says airlines accommodate their elite customers first. The passengers most likely to be bumped, he says, are infrequent, economy-fare flyers. (Joe Fiorino/CBC)
The former Air Canada agent who spoke with Go Public says one way to ensure you have an actual seat on a plane is to log on to Air Canadaʼs website 24 hours before the flight to choose a seat. Or, pay a fee for seat selection when you buy your ticket.
"Anyone who has a seat assigned to their ticket when they get to the airport never has to worry about being put on standby," he said.
Harder to claim compensation
Regardless of why an airline has more passengers than seats on a flight, new federal airline regulations coming down the runway will make it harder for travellers to claim compensation if theyʼre denied boarding, says Gabor Lukacs, founder of a Canadian advocacy group called Air Passenger Rights.
Currently, airlines must seek volunteers to give up their seats before denying anyone boarding. Passengers who are involuntarily bumped are entitled to compensation — up to $1,350 — depending on the airline, destination and length of the delay.
The new proposed regulations provide higher compensation, but require the passenger to prove they were denied boarding due to an oversold flight caused by a situation within the airlineʼs control.
"This is impossible to show," Lukacs said.
"Passengers donʼt have access to the airlineʼs reservation system. They donʼt know how big the aircraft is. They donʼt know how many seats were sold. Moreover, in situations where the airline moves passengers against their will to other flights, it is going to look as if the flight was not oversold."

Lukacs says Canada should be emulating European standards, where anyone with a valid ticket who doesnʼt get on their plane is considered to have been denied boarding — and is eligible for compensation.
"In Canada there is no excuse for drafting a definition so narrowly that people who pay their hard-earned dollars for their seats wonʼt get compensated when they are denied boarding on their flight," he said.
ʼHeavy penaltiesʼ coming
Minister of Transport Marc Garneau says the new regulations wonʼt ensure everyone has a guaranteed seat, but will hold airlines responsible for denied boarding.
"Theyʼre not going to get out of anything," Garneau told Go Public, pointing to stiffer penalties in the new regulations.

He says there will be "heavy penalties" if a passenger is denied boarding because the airline oversold its flight — in some cases up to $2,400.
Lukacs says bigger fines are meaningless if passengers canʼt prove they qualify for compensation.
His organization has started an email writing campaign for people to tell the federal government that the proposed air passenger rights regulations are inadequate.
So far, almost 5,000 people have participated in the campaign. The deadline for public feedback on the draft regulations is Feb. 20.
"Canadians are fed up with how airlines treat them," he said.

This blog series focuses on the collection of device data by various popular mobile apps. Data is often collected in the name of advertising, error monitoring, fraud detection, and social media integration.
Air Canadaʼs mobile app, which allows their customers to book and manage flights, tracks users with Glassbox Digital analytics. This enables Air Canada to determine device characteristics, collect precise location information, and take screenshots of the usersʼ device.
Air Canada is the largest flight provider within Canada, setting a record of serving 48 million customers in 2017. Of these customers, approximately 1.7 million have registered an account within the Air Canada mobile app.
On August 28th, 2018, Air Canada posted a notice to their mobile app users, alerting them that "20,000 profiles may potentially have been improperly accessed" and that they would be asking all 1.7 million users to reset their password. In this notice Air Canada states that any credit card information that is stored is done so in compliance with security standards set by the Payment Card Industry (PCI).
Air Canadaʼs description of user data stored by their mobile app
The Glassbox tool captures many screenshots during a userʼs session on the Air Canada mobile app. Glassbox has accounted for the fact that userʼs may enter sensitive data into fields and allows businesses that use their tool to define obfuscating black boxes.
To do this properly requires a large amount of testing to assure that all sensitive fields have been covered appropriately under all circumstances. While Air Canada does configure a list of sensitive data fields which should be covered with a black boxes, many of the fields are still captured within session screenshots.

Transparent black boxes
By attempting to implement the black boxes, Air Canada implicitly acknowledges that various fields within their app will contain sensitive data and that this data should not be captured in screenshots. This obfuscation of sensitive data is potentially done to ensure it is not stored within a database of screenshots.
However the configuration which Air Canada uses to specify placement of black boxes is not extensive enough and almost every black box used to cover sensitive data is captured in screenshots. Included below are two specific examples of poorly implemented obfuscation.
In the first example Air Canada attempts to block the collection of credit card information when a user associates a credit card with their account. Initially obfuscation is performed correctly with black boxes, however subsequent screenshots capture the revealed information. If these screenshots (which contain credit card information) are stored by Air Canada or shared with the third-party Glassbox, Air Canada could find themselves violating the standards set by the Payment Card Industry.
The second example shows the collection of passwords via screenshots. Air Canada attempts to cover the password form when logging in. However they do not obfuscate the initial setting of the password during account creation or resetting the password when forgotten. This finding is caveatted that I had to reveal the password using the show password functionality, but I would be fairly certain that any user who used this would have their password captured as a screenshot.
If this data is saved it would go against industry standards which state that a password should never be stored.
What users can do about it
I donʼt know why Air Canada takes screenshots of their usersʼ activities. There is the potential that it could be used for quality assurance purposes or dispute resolution. Air Canada would be able to see when their appʼs user interface is broken or substantiate displayed flight prices when a user claims they saw a different price.
If any user feels uncomfortable with the data collected via screenshots by Air Canada they should attempt to block connections to glassbox.aircanada.ca. This should be possible through DNS settings within your home router.
Air Canada is unsuccessful in obfuscating credit card and password information. As a result, sensitive data is being captured as images and potentially stored. Although the data is not in text format, sensitive data stored as images can just as easily be harvested and leveraged if the database is ever compromised.
While there may be value in documenting user activity through screenshots, there is also a large amount of risk that the screenshots may capture sensitive data. Air Canada has attempted to mitigate this risk by configuring black boxes to cover sensitive fields. However this attempt has failed, potentially condemning a users sensitive data to residing in various screenshots stored by Air Canada.

Currently -6º F
School cancelled second day in a row. At least the sun is out. Tomorrow the forecast for high temperature is -11º F. The low will be -31ºF. School will no doubt be cancelled a third day in a row.
I probably won’t be on my #bike until Thursday.

The Five Elements and Their Attributes
The rishis perceived that in the beginning the world existed in
an unmanifested state of Consciousness, avyakta—meaning unmanifest.
From that state the subtle vibrations of the cosmic, #soundless sound Aum manifested.In this way, Ether manifested into the four elements of Air, Fire, Water, and Earth.
From the subtle #vibration of #Aum came the #Ether or #Space element.
This #ethereal #element then began to move and through its subtle movements created
the Air element, which is Ether in action.
The movement of Air produced friction and through friction heat was generated.
#Particles of this heat combined to form intense light and from this light the Fire element emerged.
Thus, Ether produced Air and it was #Air that further manifested into #Fire.
The heat of Fire dissolved and liquefied certain ethereal elements, forming #Water
that then solidified to form the molecules of #Earth.
From Earth, all physical bodies for organic living beings were created,
including both the plant and animal kingdoms.
Earth was also the origin of all inorganic substances that comprise the mineral kingdom.
Thus, out of the #womb of the #FiveElements all matter was born.
The five basic elements exist in all matter.
Water provides the classic example: the solid state of water, ice, is a manifestation of the Earth principle. Latent heat (Fire) in the ice liquefies it, revealing the Water principle. Eventually water turns into steam, expressing the Air principle.
The steam disappears into Ether or Space.
Thus the five basic elements—Ether, Air, Fire, Water, and Earth—are all present
in one substance.
All fiveMan is a microcosm of the universe and, therefore, the five basic elements present in all matter also exist within each individual. In the human body, many spaces are aspects of the Ether or Space element.
originated from the energy within Cosmic Consciousness and all five are present in all matter in the >universe. Thus, energy and matter are one.
The spaces in the mouth, nose, gastrointestinal tract, respiratory tract, abdomen, thorax,
capillaries, and tissues are all examples of Space.
Air is the element of movement. All movements involve Air as an element, because it alone moves everything. Any time there is motion, it means Air is present.
The nature of the elements themselves determines the nature of physiology.
Within the human body, Air is present in the pulsations of the heart and the expansion and contraction of the lungs. Under a microscope, even a single cell can be seen to move. Response to a stimulus is the movement of afferent and efferent nerve impulses, which are sensory and motor movements respectively.
Movements of the nervous system are also governed by the Air principle present in the body.
The third element is Fire. The source of Fire and light in the solar system is the sun.
In the human body, the source of Fire is metabolism.
Fire works in the digestive system as well as in the gray matter of the brain,
where Fire manifests as intelligence.
Fire also activates the retina to perceive light.
Therefore, body temperature, digestion, thinking processes, and vision are all functions of bodily Fire. All metabolism and enzyme systems are controlled by this element.
Water, the fourth element, manifests in the body as the secretions of digestive juices, in the mucous membranes and in plasma and cytoplasm. Water is vital for the functioning of all the systems of the body.
For example, dehydration resulting from diarrhea and vomiting must be treated immediately to protect the patient’s life.
Earth, the fifth element, is also present in the microcosm of the human being.
Life is possible on this planet because the Earth holds all living and non-living substances to its solid
surface. In the body, all solid structures are derived from Earth.
Beginning with the principles of the Stirling engine, SoundEnergy's THEAC thermal acoustic engine takes heat – either industrial waste heat or solar heat – and turns it into powerful cooling without requiring any other power source. This completely renewable technology could prove highly disruptive.

According to a recent study published in the journal Science Advances, air pollution not only affects air quality, but it also changes the pathways along which new particles are formed in the atmosphere.
