I'm surprised nobody is discussing a possible electrical failure in the context of Boeing's quality problems and whistleblowers and so on. Would that be against the PPRUNE rules? If anyone's interested, here's an article to get you started https://prospect.org/economy/2025-06...hed-air-india/

A thrust changed with the thrust leaver to idle is much slower and would not result in the dramatic change in performance. Thrust set to idle will not engage the RAT since the electric generators would still work. So a thrust leaver changed to idle or any intervention by Autothrust (AT) would not yield to the RAT extension. Something or someone activated a fuel cut off. How and why that happened is the big question, the investigators have to answer.
A naive glider pilot question: if fuel cut off was (inconceivably) selected, would both fuel control levers have been flipped downwards from Run to Cutoff? And if they were then immediately flipped back to the Run position, how much time would have been needed to achieve enough thrust to maintain altitude?

The 787 fuel controls do have guards on each side but they're hard to see in the photo I posted. Here's a better angle:

They are guarded. To refresh everyone's memory here's a photo from the previous thread.

Could you comment on the phenomenon of taking a planeload of colleagues and passengers with you when you kill yourself? It's so easy to commit suicide alone at home without harming anyone else. That's what most suicidal people do.

I'm sorry to say that OhForSure's suicide theory fits well because:

1) like many suicidal people, the captain may have planned his death in detail. He would have known that cutting the fuel at this altitude would guarantee that the engines could not produce thrust before the aircraft crashed. He would have known that if the other pilot seized control it would be impossible to land in an area empty of buildings. And he would have known that he would be instantly rendered unconscious upon impact, with certain death at the same moment or shortly afterwards.

2) he may have wanted the investigators not to reach a firm conclusion of suicide so that his family would receive an insurance payout, and his family, friends and colleagues would not be vilified or feel guilty about not noticing his mental condition. His mayday call may have been carefully calculated to deepen the mystery of the final moments. He may have chosen fuel starvation at low altitude rather than a vertical dive from cruising altitude because the latter would have looked more like suicide and he'd have had the additional hurdle of preventing the other pilot from saving the day.

Is anyone finding the archived copy impossible to load? I was unable to get at it until I used a VPN to pretend I was in the Netherlands. I could paste the whole thing here if it would help, but it's pretty long. Some people would regard most of it as irrelevant.

Is it actually possible for dementia to be ruled out? Even if the captain passed his medical a day before the flight, can it be guaranteed that dementia did not begin that morning? If not, the investigators don't have to default to suicide, even when all other scenarios have been discounted. Problem solved.
