> I'm just reciting what's been shown in videos

Of unknown provenance, with unknown visual artefacts, et cetera. Even if completely legit, with context and thus chain of causation obscured to the point that discerning ultimate and proximate causes is impossible.



Agreed, but it doesn't look like AI. Video(s) look real to my untrained eyes. Everyone is going to speculate regardless of the top level disclaimer. I rather just at least present what data is available as of now.

The city the incident took place in has a subreddit. Feel free to go take a look and judge for yourself. It's a bit NSFW at the moment.


> present what data is available

It’s not. It’s one video of unknown quality and relevance, picked somewhat randomly out of all the other available videos and data, the most relevant of which aren’t publicly available.

> Feel free to go take a look and judge for yourself

It’s the usual emotional coping through baseless speculation. There are healthier ways to deal with uncertainty amidst tragedy.


Some people trust their own thinking to judge what they see.

We know it called mayday and then lost communication. It also stopped transmitting GPS data.

Looking at this it likely lost all electric power. The electric power comes from generators driven by the turbines.

If you lose both turbines you lose electricity. You also lose the hydraulic system so you can not get in the gear or change flaps.

Occam's razor checks out.


Don’t these Dreamliners also have back batteries?


They have a RAT (ram air turbine) that deploys automatically under specific conditions. It’s basically a turbine providing electric and hydraulic power. It was almost certainly deployed on the accident flight. It will only power the most critical equipment, though. Possibly, that does not include the ADS-B transmitter (which broadcasts position and related data).


This analysis is convincing about being able to hear the sound of the RAT from the crash video: https://www.youtube.com/watch?v=SbDJjgN7Xbo


Even on light GA aircraft the radio will run for an hour on the starter battery. This narrative doesn't sound realistic.


Yes and many pilots being walkie talkies in GA as backup. Not sure if airline pilots do this though. And its kinda hard to root around for it and fiddle with it while trying to keep an unpowered jetliner in the air. They're more for emergencies where the radio is the only problem.

By the way, the age old rule is "Aviate, Navigate, Communicate" in that order of priority. So it could be they just had their hands full with the Aviate part.


Yes, lithium ones, those were the ones that kept catching fire then the 787 was just out.

I guess they're just for the time until the RAT kicks in. Or to augment it.

Ps there's also the APU, a small turbine in the tail for generating electricity.


I wish every news was held to this standard.


The industry would be substantially smaller. This runs counter to the interested of every existing industry participant.


I agree. Not sure if there's any possible alternative worlds where the checks and balances shake out something better either sadly.
