After two years of immersion in the subject of jetpacks / hoverboards of wings, I always say my position in lectures: the future is with the “wings”. Neither the Englishman Richard Browning with his dress of the iron man, nor the Frenchman Frankie Zapata with his hoverboard flyboard can compare with what very, very soon the Swiss grandfather will get up with a sweet surname for our ear (Yves Rossi). Last year he turned 60 years old, I hope he still flies 60 years.
On December 19, 2019, Yves Rossi posted two videos showing vertical soaring and training. This is a very significant motivating step that will inspire many developers to create their own versions of automation to stabilize and control flight / hover on a jet stream.
On the net, I dug up that the first flights on the wing of Yves Rossi began in 2004. The wing was folding so that you could go out into the small door of the plane. And the turbines also turned on on board the aircraft, and as soon as they gained momentum, Yves Rossi jumped out and laid out the wing.
Here is an old video:
