I want to see that fly
Here the Snecma C-450 Coléoptère
the only ringwing VTOL that ever fly
Why a wing in form of ring ?
the wingtip produce drag and turbulence. wat slow down a Aircraft
with out wingtips the Aircraft get much faster. (up mach 3 and faster)
Note on C-450 Coléoptère
this was a French tailsiter VTOL design
the only prototype crash in testflight during landing
