The C2D is a simple fixed wing airplane. Far less to go wrong.
How many decades & crashes did it take to bring the V-22 into the inventory?
What’s the Class A/B/C/ accident rate of the V-22 compared to the tried & tested COD?
I think the Greyhound has foldable wings that allow for a smaller footprint when it is stored on a carrier. I don’t think there’s much you can reduce in the Osprey’s footprint, can you?
