one witness said
one witness indicated that the engines came up to full power as the plane hit.
if this is true, could the engines have relighted?
in a post which may have become lost in space, I asked 777 guys if there is a "ground idle" engine range that might be commanded by a ground shifting mechanism (WOW, squat switch, what have you).
also, could a lack of selecting engine anti ice while descending through clouds, followed by a quick melting of ice, sending a stream of water through the engines.
both engines quitting at 400 feet simply does not happen, and if it does, the thinking behind long range or any range twinjets might just go out the window.
