yes, pattern is full is quite right...can't stretch a glide
I would like to know what configuration the plane was in (flaps/gear etc)
one could think fuel exhaustion...but there was a post crash fire reported
one can think of fuel starvation (boost pumps on we hope)...however, if the crew had been crossfeeding and forgotten....well, that is one way to lose an engine
indeed, I will go out on a limb and say: crossfeed and run both engines off one tank, run tank dry and both engines go out...oops...even with fuel in the other tank
so...that's my theory for now
