Talking about Flying, look at this baby:
and Franck Cammas trying it :
That's a modified F18. Not yet competitive but you never now. Some years ago they say that the Moth on foils was only a stunt and that would not be competitive, and look at them now.
I guess the problem here is that it is made to fly on the two foils. That's too much resistance. They have to fly on a single foil to diminish drag. An equilibrist act...but that's racing
