Not going to get drawn on possible reasons for this crash (that's for investigators), but I would encourage you to make a complaint to the BBC regarding the fact that the BBC News reporters trespassed onto the crash site and probably contaminated it. Their reporter was up-front in admitting that they explored it before the police kicked them out. And even more fundamentally, if they weren't helping with the rescue then they were getting in the way of emergency responders.
Regardless of whether or not the cause is clear cut or not, they should know better than to go trampling around a crash site when they could easily film from the edges. Normally I'm very happy with BBC News as a source of information but this was unacceptable, in my opinion.

like everyone else have no evidence that TMCA played a role but given that it is one of the few systems with the ability to cut fuel to the engines, here are some thoughts on how signal processing could have extended the window of when TMCA could bite. In

Another post referenced the RAT only supplying electrical power after 10s - I find that hard to believe, not instant obviously because there has to be some stabilisation time and startup/boot time but it would imply the LH flight instruments would only be active very late.

For what it's worth, if the fuel control switches were rapidly cycled as per the dual engine failure memory actions, the engines should both have restarted and recovered full thrust within a matter of seconds. This is part of the certification and Rolls Royce publish the procedure (unofficially) as a last-ditch attempt to recover an engine that's experiencing a locked-in surge condition.

This is - in my opinion, I must stress - an incredibly clumsy move by an Air India pilot. I think the impartiality of the investigation was always dubious, and now even more so.
I can quite believe a fuel control switch not latching in position, because I've seen it happen myself when going from run to cut-off where someone let it sit on top of the raised lip between positions instead of deliberately moving it to cut-off. I can just about conceive of a case where someone did this on engine start and the switch flicked to cut-off with the thumping of the nose wheel over a rough runway. Do I believe that it could happen simultaneously to both switches? No. On top of that, when did they discover this? Were they flipping the switch during engine start? Did they abort the start and experiment with the switch? Why didn't they get engineering assistance? This is just spectacularly dodgy decision making. Subjects

2. This is taken into consideration at the design stage and isn't an issue. Subjects
