Any details on the reason for the Air India incident? Seems to be a bit early, but even by now there is some data from tools like flight radar etc. @aviationdoctor.eth

What I saw from the two videos circulating is an aircraft sinking (not stalling). That only happens when lift < weight. Some people have said that the flaps/slats were retracted. I find it hard to confirm from the videos, though that would certainly explain the sinking. It still leaves unresolved the question as to how it took off in the first place; it’s difficult to imagine taking off without flaps. One option is an erroneous retraction of the flaps (instead of the gear) right after takeoff, but that’s a very gross mistake. Other option is bilateral loss of engine power. Statistically unlikely unless dual bird strike (like in the Jeju Air crash). Fuel contamination other possible cause but even less likely.

I agree with everything said here. I’m an ATP with experience flying a few different jet types. I do NOT have experience in the Boeing 787 cockpit. The one thing that bothers me is that all these aircraft have an EICAS that will alert the pilot if the TakeOff Configuration is valid. So while I do see how this looks like the pilots may have taken off without flaps, possibly engaged autopilot early, and then stalled, I don’t know how they got past a warning about the configuration selected. There are some aircraft that require a zero flap take off with a very long runway when operating at high altitude airports but not the case here as I read. Really sad situation and even though we don’t know what happened for sure yet, just the speculation is a great reminder that you should ALWAYS run the checklist and run it again when dealing with abnormal, interrupted, or rushed situations.
