That actually pretty cool!
It looks dangerous as hell! The prop in back where it really had to be with the canard in front would seem to make it highly problematic to control, It probably needs a computer assist. If it lost power, might gliding control suffer?
I wouldn't want to get in one of these things unless it had a parachute to bring it down safely.
Back in the early years of flight (or at least back in the 50's) it was theorized that by gong 3-dimensional there would be a whole lot more room in the air than on highways so it would be safer.
But now we know it ends up not working out that way since airplanes tend to need airports to land on and take off from, so they concentrate over them and we have too many near misses. And that's reality even though we now have planes carrying many hundreds of passengers instead of maybe two or three at a time.
