Vortex Ring State is well understood and no longer the problem it was early in the V-22 program.
The V-22 is replacing the C-2 Greyhound in Naval Carrier Onboard Delivery (COD) service, so I think the V-22 is here to stay.
Damn! That makes me feel really old.
The CODs to my carrier were “Willy Fudds”: WF-2 aircraft.
