Security camera footage shows take-off and crash of Air India plane in Ahmedabad
One theory circulating online is that the pilots may have accidentally retracted the flaps instead of the landing gear. Apparently that would result in kind of a flight path seen on the published videos.
While this cannot be confirmed or ruled out with the information we have, in my opinion the available videos seem to kinda support this theory. Initially the aircraft appears to take off and climb normally, but for some reason the gear is not being retracted when usually it would be retracted right after the takeoff.
Naturally the gear could be forgotten or left intentionally down if there were a dual engine failure right after takeoff, for example, but as the videos show no evidence of this, I'm more inclined to believe in simple pilot error.
I'm not an expert, but pretty much every plane crash expert on the planet is watching the same footage and saying they don't know what's happened.
It's absurd to suggest the pilots accidentally retracted the flaps and no one figured that out yet.
Damn, did I miss the plane crash expert unison chant again?
I don't get what you mean by "and no one figured that out yet." As you said yourself, no one knows what happened yet. Pretty much all we have at this point are the videos, and all we can confirm from them is a rough flight path of the plane and that the landing gear remained down after what appeared to be a normal takeoff. I haven't seen any footage that clearly shows the state of the flaps with any certainty, but please correct me if I've missed something.
In my mind, that leaves us with three possible scenarios:
From the two scenarios (pilot error, engine failure) that fit the flight path from the videos, the option one seems more plausible to me. But that’s just my armchair opinion, it doesn't mean anything. All we can really do is wait for the investigation and the preliminary report.
I did see one person commenting on the other video that they could see the flaps were in the wrong position. And it is conspicuous that the landing gear was not retracted - though could that be because the pilots realized they were in trouble and would need to attempt a crash landing, or were too busy with whatever else had gone wrong?
Are the 787's controls arranged in such a way that you could accidentally retract the flaps instead of the landing gear?
Not in a sense that someone could just grab the wrong lever in the dark for example. The levers are in different parts of the cockpit and also shaped very differently. But we humans can do all kinds of weird mistakes that are hard to explain. Almost everyone has experienced this sometimes. Think something like searching for you phone while it's in your hand. Afterwards it's very hard to explain why would anyone do such a silly mistake but it still happened. This would be similar.

According to type rated pilots the 787 doesn’t allow you to retract flaps immediately in critical flight after takeoff.
I think the simplest explanation, and the most likely one, is the pilots were too busy dealing with whatever shit was hitting the fan to raise the landing gear.
And, in my view, that's a loss of engine power for whatever reason, possibly bad fuel.
Flaps are typically retracted not long after takeoff anyway, every flight I've been on has done that.
There are minimum airspeeds the aircraft must reach before the flaps can be safely retracted. I don't know the exact numbers, but assuming a standard flaps 5 takeoff for B787, retraction to flaps 1 would occur around 1000 ft by earliest, that's typically 20 to 30 seconds after the takeoff.
