I can’t imagine a safe distance would be that much, if things go wrong these guys are more or less just on a ballistic trajectory to the water below. That and with the number of camera drones that would zip around an event like this I’m sure watching wouldn’t be an issue.Kind of hard to see from a safe distance.
I wonder how you would transition from vertical to horizontal flight. Huge spoilers? Fold the wings up?These guys and Yves Rossy need to combine forces. Foot launch flying jet pack-wing.
Vertical climb until the airspeed over the wings is larger than the stall speed, followed by a pitch-over to horizontal flight. For the reverse, pull up into vertical flight, let speed bleed off to zero, then back down. All of this is the same as the old "tail sitter" VTOL aircraft. It's just that, since the pilot is standing in vertical flight, he'll have a much easier time judging the landing.... I wonder how you would transition from vertical to horizontal flight. Huge spoilers? Fold the wings up?
... But I suspect the problem is they have a very short range and make an awful lot of noise.
These being turbofan powered, I suspect they have "better" range than the older jet-pack designs, but yeah, since the most-likely role would be "covert", the noise is probably the issue.... it was also so loud that it was useless in that role. ...
