The Swiss Yves Rossy, aka "Jetman", and the French Vince Reffet flying through the clouds with a rigid wing, providing a real sense of freedom. Remember, Yves Rossy is the inventor of the rigid wing. With a wingspan of 2.4 meters, it is equipped with 4 reactors to fly like a bird to a maximum speed of 300 km/h. The flight takes place after being dropped by a helicopter. And for landing, it requires the use of a parachute .
