Lightly loaded, either can do a full range of hover maneuvers. Forward,
backward, sideward, up and down. Heavy, not necessarily so. But then, the
same is true of conventional helicopters. . . .

Just a question-- how does the X-15 or the V-22 compare to a real
helicopter when hovering? Can they do helicopter style manuvers, or
are we talking more just up and over on the way to horizontal flight?
