The Genius Leonardo da Vinci wrote 1485 in his notebook „if a man is provided with a length of gummed linen cloth with a length of 12 yard on each side and 12 yard in high, he can jump from any great hight whatsoever without any injury“ In July 2000 the British skydiver Adrian Nicholas used an exact replica of Leonardos design to try the first flight from 3000 meters hight. He did more than 2000 meters in gently floating down before he swithched to his conventional parachute for the slow down to ground.
