There's footage after takeoff of it descending with the air ram deployed, no engine power, gears down, and flaps up.
TBD on the cause, but loss of engines for some reason seems to be the case.
I do agree that a lot of info comes out first week that isn't all right. I'm just reciting what's been shown in videos.
- JumpCrisscross 1y ago> 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.
- perching_aix 1y agoI wish every news was held to this standard.
- potato3732842 1y agoThe industry would be substantially smaller. This runs counter to the interested of every existing industry participant.
- perching_aix 1y agoI agree. Not sure if there's any possible alternative worlds where the checks and balances shake out something better either sadly.
- SecretDreams 1y agoAgreed, 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.
- JumpCrisscross 1y ago> 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.
- randomNumber7 1y agoSome 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.
- newdee 1y agoDon’t these Dreamliners also have back batteries?
- VBprogrammer 1y agoEven on light GA aircraft the radio will run for an hour on the starter battery. This narrative doesn't sound realistic.
- wkat4242 1y agoYes 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.
- hanche 1y agoThey 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).

- leetrout 1y agoDo you have a source for this footage or are you referring to the video everyone is recirculating?
- ikekkdcjkfke 1y agoWell, loss of engine power and gliding to a stop is not that a far fetched case. Why is there not a fuel dump button to prevent a whole trips worth of fuel going up in flames?
- Mindwipe 1y agoThey were only 600ft in the air, barely anything would have got out before they hit the ground and you'd have just set non-zero amount of innocent people on fire in all likelihood when the crash ignited the trail they'd left. There is a dump fuel button if you're not in the middle of a populated city and you're far enough in the sky you've got a few minutes.
- iamtheworstdev 1y agobecause painting an entire neighborhood in flammable fluid isn't safe... if it doesn't catch fire it'll corrode everything it touches. most planes can't dump fuel anymore. if it's a serious enough emergency you land overweight. If it's not then you fly long enough to burn it off and land below max landing weight.
- sofixa 1y ago> most planes can't dump fuel anymore. if it's a serious enough emergency you land overweight. When fuel is dumped, it's at high altitude where it just evaporates. Short haul jets can't do it, but their max takeoff weight is around their max landing weight, so it's fine. For long haul, it's not the same.
- cschmatzler 1y agoBoth slats and flaps were on maximum during the entire flight.
- hanche 1y agoThat makes no sense, and is not consistent with video evidence. Max flaps (40 degrees or so) are typically used only for landing. That is very obvious when you see it! Usual flap setting for takeoff is on the order of 5–15 degrees.
- CPLX 1y agoDo you have a link to that footage? I've seen speculation on this from very blurry video but nothing like proof. On the professional pilot forums the consensus guess is inadvertent flap retraction, instead of gear retraction, leading to inability to climb.
- cschmatzler 1y agoA 787 can still climb with flaps up and two healthy engines. In the video that was posted everywhere, you can CLEARLY hear the RAT spin, which gets deployed automatically when both engines go out.

- rurban 1y agoOr birds hitting both engines. But that must have been a big flock then
- CPLX 1y agoIt's unlikely that a bird strike with dual engine failure would occur without smoke.
