Air India crash

If someone switched flaps up instead of gear up, it would not be something as simple as wrong switch. But both operations (gear up and flaps up) are part of the normal procedures after takeoff, so it is conceivable that a flustered pilot could be mentally at the wrong place in the checklist, but this seems unlikely unless something else had really gone wrong.

(I am not sure of the normal procedure for this plane, but typically gear up is as soon as the plane is airborne and you have a stable climb, and flaps will be retracted , usually in stages, as airspeed increases, but this is very dependent on the aircraft and the airport and company procedures.)

Whatever happened the aircraft only flew for 30 seconds. There were either no flaps set, or very minimal. (5?) No way that full flaps would retract in the time that the aircraft was off the ground.

i think that makes engine failure more likley

The only thing really clear in that vid that I can see is the gear was down. Can't really see the flaps, but that could be telling in itself as they are big items. The climb out never seems stable to me, but that could simply be my own projection. Pity there was no sound.

Never seen this guy before. I'm putting this here FYI.

Of course, it's all speculation, but the hardest thing to understand, at least for me, is why all the redundancies built in could fail, if indeed they did. That last vid mentions a MAYDAY call. Doesn't rule out pilot error, doesn't imply it either.

In that last video he says that there are 3 ways that the RAT can deploy. What he doesn't say is that it can also be deployed manually.

Noticed that. I wondered if they had time to deploy it. Didn't have time for much else.

Although I still look at this place from time to time, it becomes clogged up with basic BS from would be experts. I will post the following as it presents a new angle, albeit not from a pilot:

Boeing TCMA Patent US6704630B2

There is one system implemented in the 787, that has the authority to shut down the engines, based on software subsystem decision. Interestingly - according to the description in the patent below - the same TCMA software package determines the shutdown decision, in both redundant subsystems.

It couldn't have. Could it? Won't go well for Boeing if it did.
