I'm not so sure the Osprey will turn out to be foolhardy at all. The early problems seem to have been worked out, just like what happens with any new design. Nobody knows, but I hope it works out well.
The concept of the Osprey is a good one. Higher speed transit than a CH-46, longer range, but still about the same lifting capacity and mission capability. I hope it works.
V22's are being flown all over the place here in the Panhandle of Texas. Bells final assembly for em is in Amarillo and they are working very well thus far.....
As to the boneyard birds being brought back that's why they are there....The system works as designed.
