Jean Boulet (aviator)

Jean was trained in the United States earlier in his life to become a military pilot with the French Air Force, he was one of the first foreign pilots to fly a helicopter in the United States Air Force. Over the years he would become one of the greatest pioneers in the history of rotorcraft flight testing.^[1]

Boulet set several rotorcraft records^[2][3] for distance,^[4] altitude^[5][6][7] and speed.^[8]

On 21 June 1972, Boulet set the world record (still valid as of 2020^[update][7]) for the highest altitude reached by a helicopter, when he piloted an Aérospatiale SA 315B Lama to an altitude of 12,442 metres (40,820 ft).^[9] When he reduced power and began to descend, because of the extreme cold, the engine flamed out, and Boulet performed the highest ever full touch down autorotation, landing with absolutely no power.^[10] This high altitude autorotation also set a new world record.^[9] Because of his unpowered flight back to the ground, he is also credited with the largest altitude flown with an autogyro.
