The last thing a dead stick Crane driver needs is to remember that the APP is not flight rated (that limit is because it is not fire zone protected and so is not really a flight "engine"). I trust that every Crane driver in the world knows that if both engines flame out, he can start the APP and try to relight them!
I doubt that any forward speed the crane can get to would provide enough oomph to rotate the engine enough for a start, but I could be wrong (never got a Crane checkout).
The trip down from 36000 feet was a long long one, PT6ER, think about it! At 2500 FPM it would take 15 minutes!
