Earlier quoted context omitted.

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.)

Do you have a voice recording of you doing your entire job, every day of your life?

Hundreds of people don't die when I screw up.

> Given how cheap flash is these days How cheap is flash that will survive a sudden stop from 400mph to 0 mph in no seconds flat, will survive a post-crash fire, and/or submersion for years in salt water? Flash data retention at high temps is TERRIBLE (and gets worse for MLC/TLC/etc), see any flash datasheet. It is NOT nearly as simple a problem as you might think. Yes, it is a solvable problem, but please do not dis…

This isn't a technical limitation though, the European standard for airplanes newer than 2021 is in fact 25 hours [1].

HN isn't a monolith, and it certainly has better representation of anti-union sentiment (ie. they don't all get downvoted to oblivion) compared to other discussion forums (eg. reddit).

What’s missing from this accident investigation without the recording?

There are software engineer jobs where you need to keep your camera on during work hours to show you are in your seat.

Yeah, but nobody applies for those.

These jobs do not attract the best software engineers.

My job does not involve direct responsibility for the immediate life-or-death of hundreds of lives.

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.

This is the reality for a large number of truck drivers who bear a significantly lower responsibility.

Great link!

I like how that comment is from an anonymous source, but now that the NTSB preliminary report is out, it seems thoroughly corroborated to me. The dates of certain events and the reason for the door's removal—er, "opening"—both match the comment in your link.

Thanks.
