The largest US pilots union opposes it on pilot privacy grounds. (To be clear, I think having an expectation of vocal privacy while you are in charge of an airliner is absurd.)

My wife ridicules me because when we went out to eat, before a multitude of children , I would often say “nobody ever tipped me as a meat clerk when I was working in 45 degrees elbows deep throwing away and scraping rotting meat from the shelves and gutters and then serving ‘fresh shrimp ‘ and organic grass fed filet mignon” when I felt expected to tip 20% for an already over priced meal.

As my first boss, meat clerk young lady, told me “shit rolls down hill.” More powerful people tend to get shitted on less. It was a motivation to move up.

But I still think it’s shitting on people to expect or accept constant recording of everything mundane thing while awaiting the exceptional [screw up]. Pilots are more powerful than Amazon warehouse workers but recording every breath, every whisper, ever fart is undoubtedly shit in a warehouse or a cockpit or an operating room.

Then again, the only way I could accept it is if everyone is recorded all the time and it was all public or at least FOIA able for many people. Especially the government and universities and Wall Street other wise it’s just a way to control and hang things over peoples heads.

As to the tipping grumpiness I grew up partly in the 3rd world where tipping 50 cents was a great tip and I’m cheap and didn’t/don’t make tech bro money. I found the ultimate solution was to just not eat out so much except for truly special occasions. I’m sure there’s a lesson in there too somewhere.

These jobs do not attract the best software engineers.

They could with sufficient pay.

The intersection between employers who demand to film you being in a chair and employers who shower their employees with substantial lucre is the null set.

I doubt the jobs where you don't enjoy any level of trust are the ones where you get paid well or get any kind of dignified treatment.

I recently saw a job ad for a JavaScript specialist where the position entailed having screenshots and keyboard + mouse tracking to monitor your working hours. It was a freelancer position, so the hire would handle taxes and health insurance, no equipment would be provided and working hours would start at 08:00 German time sharp for at least nine hours or until you "finish the daily tasks". Pay would however be for 189 hours per month, no compensation for sick leave/holidays/vacation, and you'd be paid via upwork.com (with you paying Upwork's fees) in US dollars.

The rule (edit: in Europe) is now 25 hours for aircraft over a certain weight, though it is not (currently) retroactively applied to existing equipment. https://www.federalregister.gov/documents/2023/12/04/2023-26...

That document is an in-progress proposal to amend a rule, no? I think there was strong opposition to this rule before this accident flight, and the blowback from the missing data here might be strong enough to be able to get it passed anyway.

> the blowback from the missing data here might be strong enough to be able to get it passed anyway

Nice pun.

What do you think would have been gained from the CVR data in this case? Do you think pilot error had anything to do with the door-plug failure? Do you think the CVR was left running on purpose/accident?

If I were one of those pilots, the first words out of my mouth probably would have been, "what the $&#*?!" followed by whatever procedure had been drilled into me for rapid-depressurization. Given the scenario, I wouldn't lose any sleep over forgetting to shutoff the CVR in the mess of getting everyone to safety.

Depressurization happened around 17:12:33 PST but the aircraft continued to climb until 17:13:41 PST, and the autopilot was configured for 10k ft at 17:13:56 PST. Why did it take the pilots a full minute to begin an emergency descent after the failure? I would expect that the nature of the accident would be clear nearly immediately, at least in the need to descend the aircraft.

You can't leave your assigned altitude/trajectory without coordinating with ATC. Otherwise you may collide with another plane, which would make a bad situation worse.

Aviate comes before navigate and communicate. The pilot in charge is ultimately responsible for the safety of the aircraft, not ATC.

It was enacted in 2021 for some aircrafts. Not sure what the change of that proposal is, might expand it to more.

Clearance + they were probably putting on their masks, and other tasks.

Privacy from an NTSB accident investigation is absurd. Privacy from your boss snooping you is reasonable.
