But a single hit at their common meeting point is the same as as single point isn't it?
There is only so many ways to separate critical bits....and I would assume the Osprey is prey to that problem if you introduce something like and RPG that can knock out a Tank and make huge holes in aircraft.
Dare we bring up the subject of autorotational capabilities of the Osprey?
Did not the Marine Corps say it wasn't really necessary as a dual failure of engines was a one in a billion chance.....shortly before an aircraft on a flight out west had icing problems that caused both engines to fail. Fortunately the aircraft was at altitude and in airplane mode and had time to restart the engines on its way downhill. Had it been in another situation it could have been a lot different.
