tubby, suggest you stick to what you know: commercial flying.
The V-22 certainly seems to be a troubled type.
Are you ghost writing for David Axe? The year is 2017. Suggest you look at mishaps per flight hour, which is the standard that the USN uses for assessing if there are problems or not. I'll ask you this question: a while back a UH-60 Army Black Hawk went down on a golf course in Maryland. Tail rotor failure. One dead. Where were you then with your "troubled type" noise?
Hey, how about this? Go read the news. About a year ago an Army Apache went down near Galveston, Texas.
The freaking Rotor Blade came off in flight. Two dead.
(There's a thread on PPRuNe about it). I guess according to Tubby, it's a "troubled type."
