Lost in Saigon;
The original notion posited by some was, the engines continued to run post-crash and the resultant high thrust levels from the departed engines was the reason they were so far ahead of the wreckage. I think that is an incorrect assessment of why the engines ended up where they are. What do you think?
I think the engines were simply carried forward by inertia after they broke free.
It is possible that a small amount of residual fuel kept the engine running for a second or two, or maybe just the high pressure turbine spooled down as the engine came to a stop forward of the aircraft.
As for the photo of the smoke/dust behind the engine, it could be interpreted different ways. Some one pointed out that it could have been snapped at just the right moment as the engine was still traveling forward across the ground.
I think it is also possible that there was smoke trailing out of the engine as the high pressure turbine spooled down.
