^ design and concept wise, maybe. But dont forget that the basic concept of the rotory winged craft dates back, at least in part, to da vinci lol.

Aircraft "age" is an issue of frame stressors over time isnt it? (not being snarky, really asking. I know some of y'all work air craft and will know better than me)

Ospre is a "first of concept" craft. If its development and deployment fulfulls strategic/tactical/logistics needs (issues I really have no clue on) shouldnt it be persued? And if it no longer fulfills any of those needs, should it be dropped? Or should the concept be worked out to completion, just because it's a new thing and might be useful later?

Experiments with rotory winged craft started in the '30s (or there abouts) and we didnt get a real deployment and use of em until Korea in the early '50s. And the concept of "air mobile" warfare wasnt realized until Vietnam in the '60s.
