This is information about the first flight in world: In 1906, two French brothers, Jacques and Louis Breguet, started experimenting with airfoils for helicopters and in year of 1907, those experiments resulted in the Gyroplane No.1. Although people are not sure about the dates, but sometime during 14 August and 29 September 1907, the Gyroplane No. 1 lifted its pilot up into the air about two feet (0.6 m) for one minute. Meanwhile, the Gyroplane No. 1 was proved to be quite unsteady and needed a man at each corner of the airframe to hold it tightly and steady then it can fly. For this reason, the flights of the Gyroplane No. 1 are considered to be the first manned flight of a helicopter, but not a free or untethered flight.
