Spent a week down at New River back in 2001 (working with CH-53 unit) - they would drag the V-22’s out of the hangar and hose the bird crap off of them then drag ‘em back in (they were grounded at the time) - all of the marines i spoke with hated the Ospreys.
They don’t hate them So much anymore. And trust me (I live in the flight area), they fly them plenty now.
