Seems to be pretty much like a Chinook at the same point, speed, and all when an RPG takes out the Synch shaft is it not?
We could agree to that statement if we would equate a lucky "shot to the side of the nacelle, taking out the engine
and ISS half shaft" with "shot anywhere on a chinook that takes out the sync shaft"
The chinook fails catastrophically with a
single point of failure. Rotor self annihilation, no autorotation.
The V22 needs to fail
BOTH the engine and ISS shaft to be in a similar situation.
