Honestly, have you ever actually spoken to Opsrey pilots? I have on many occasions at airshows, and every single last one of them enthusiastically loves the airplane. It's no show.
There we have it.....unimpeachable sources!
Sans....have you ever considered what happens to a Marine that disses the Osprey in public at an air show? Can you say..."End of Career", prolonged posting to the Infantry, speedy exit from the Corps?
It just ain't the done thing!
