Air India 787 Crashes in Western India

"The flight was under the command of Capt. Sumeet Sabharwal, a Licensed Type Commander with 8,200 hours of experience, and First Officer Clive Kundar, who had 1,100 hours of flying experience. Investigation into the crash is ongoing "

What could it possibly be? Got to give them credit for putting it down wings level.

Premature flap retraction? Can't imagine why, though.

I can't see someone raising the flaps instead of the gear.
But looking at the video, you could be right. Or even a takeoff without flaps, flying in ground effect, until it couldn't.
I hope it's not a stupid, as I doubt there are any alive.
 
For sound comparison, here is a 787 landing with the RAT deployed, the sound is quite distinctive:

 
"The injured are being taken to the nearest hospitals," Air India added.
I'm amazed that there are injured, but word isn't exactly leaping out of India.
 
Don't read too much into the flaps. A Flaps 1 takeoff is likely an option, as it has been on every Boeing airplane I've flown. Flaps 1 is slats extended but no trailing edge flaps.

If the RAT was deployed, that would suggest a double-engine failures.
 
"The plane came down in a residential area, crashing on to a medical college hostel outside the airport during lunch hour. "
All on board dead, plus more on the ground. Worst case scenario.

Is the RAT automatically deployed on the B-787 when the computer determines it's needed?

Yes. As Larry mentioned double-engine failure, total loss of hydraulic pressure and a few other things would lead to RAT auto deployment.
 
Someone mentioned birds and both engines out. Not totally reliable, but that’s what I heard.

Just looking at our 787 manual, Flaps 5 is the minimum for takeoff (same for the 777). But as you said, I don't think the video resolution is good enough to infer what the flaps were doing during the climb.
 
There is a full video of the takeoff on Facebook

This thing was barely able to get off the ground. Def suggests performance/thrust issues
 
‘Positive rate, gear up’, F/O muscle memory has him raising the flaps, possible, still hard to believe.

Then next plausible is incorrect data entered in the FMC, rendering speeds & thrust inaccurate.

Just going by the odds, ‘likely’, nothing wrong with the plane, that couldn’t be routinely handled.

It comes in threes, may be time to get to the bunker.

I'm going with thrust. Just enough to zoom out of ground effect and then behind the power curve to impact. Flaps and gear wouldn't over power that, although the trailing edge looks clean except there are a few frames that show a deflection in the trailing edge at the flap junction. Got past the abort No Go point on the runway and they were committed to fly. Whatever happened started on the runway.

All the dust at rotation certainly seems to indicate that they were near the overrun at liftoff.
 
I couldn’t see flaps in the video. NEVER heard of a flaps up takeoff, hard to believe there isn’t a takeoff configuration warning system, not that it can’t be over looked.

Seems it would come down a LOT harder than that if loss of thrust in both engines.

Again, not definitive, but I’m in the configuration problem camp. Power too much reduced, maybe flaps, maybe a combo. Generally all things that can be easily recognized and fixed, none of which are EVER practiced.

I was a volunteer pilot at a museum, we took off half flaps. When the plane wouldn’t lift off at the normal spot, I instinctively reached for the flaps, set them and continued…

I thought it odd the gear stayed down. If I can’t climb, I’m cleaning up…

Gear (both main and nose) appear to remain down throughout the sequence.
 
The lowered gear suggests they didn’t have power to raise them, which links to the RAT noise and loss of both engines idea.
 
someone suggested interesection takeoff? 6300feet usable intersection departure per the youboobers. I can definitively see that getting boned up, as hot/humid as that whale taking off would have been. The dust plume is visible on the underun.

My Occam take is bad TOLD calculation, premature lift off due to not enough runway. They were screwed the second they pushed those throttles, if the interesection takeoff claim is true.
