Is it possible that not putting the a/c in an unrecoverable position was a factor also? Do you believe if the CH-53 was in the same scenario as the Marana V-22 a CH-53 could have recovered? (none of the other CH-53 drivers I have spoken to believe it would have been survivable, but perhaps there is some empirical data we are not aware of?)
At least a '53 would have hit upright (like the Lead V-22, Nighthawk 71 did), not inverted and ensuring that it would be unsurvivable. Below 800 feet or so, A-VRS is unsurvivable. Marana proved that.
