Too early to speculate on cause of Heathrow crash...
But do you think it could have just run out of fuel?
The fuel tanks in a Boeing 777 are in the wings which were extensively damaged, but no fire occurred. The engines shut down 20 seconds before landing, so there was no time to dump the fuel.

The accident interim report is due within 48 hours, any thoughts before that?

One passenger is quoted as saying
"There was lots of smoke in the cabin and everyone was in a panic. The two stewardesses were very calm and told everyone to sit down."
There have been other instances of commercial aircraft running out of fuel.

I believe it may have been an electrical fault. The switchover from auto to manual pilot had just taken place.
Its highly unlikely to be engine failure as the odds are astonomical both going at the same time as well.
Also the engines were still going according to eyewitnesses as they heard a terrific engine noise before crashing.

If the Flight Crew was aware of a shorted of fuel, the Captain would have signalled that he was making a landing at an airport on the continent.
If they was not aware, then the fuel gauges must have been faulty. But even so having flew all the way from China it seems very unllkey that the fuel ran out just meters from it's home runway. Did the plane stop previously to be refilled?
With the obvious danger of flocks of birds entering the engines of airliners, is it inot possible that some kind of grid or deflector could be fitted, so as to prevent this danger to the engines?

Just remembered the Kegworth Aircash when a plane came down short of the runway. That plane plane diintergrated on impact, but there was no significant fire. That accident was attributed to a malfunction compounded by pilot error. They had a problem in an engine, and they shut down the good one by mistake.

Unless the gauges were faulty, or there was more water in the fuel tanks thank normal, lack of fuel is unlikely. It has happened before, but it is possible to land and even rupture tanks without a flash fire
Windshear is a possibility, but does not fit in very well with ditching ahead of the runway with the final flight pattern that was taken
Total loss of electrical power and engines is unheard of
Pilot error if one engine failed (like Kegworth) is possible, so maybe birdstrike
The engine 'noise' heard by passengers was probably the RAT (Ram Air Turbine), which provides emergency power to the plane if the engine fails.

If the power failed as has been mention, then there would be no thrust forward or reverse. The air breaks on the wings are used to slow the plane while it is in the air. I think reverse thrust is used after touchdown.
The bird strike theory is unlikely to take out both engines simultaneously, and a 777 should be able to land successfully on one engine. Unless that then resulted in the pilot doing something wrong to compensate.
I'm no expert,
