| | Breguet "Gyroplane" helicopter - development history, photos, technical data |
 | | It cannot, therefore, take the credit for being the first helicopter to make a free flight, even though the ground helpers contributed nothing towards the lifting power of the rotors; but it was the first machine to raise itself, with a pilot, vertically off the ground by means of a rotating-wing system of lift. |
 | | Basically, the Breguet machine consisted of a rectangular central chassis of steel tubing supporting the powerplant and the pilot; from each corner of this chassis there radiated an arm, also of steel tube construction, at the extremity of which was mounted a fabric-covered 4-blade biplane rotor, making a total of 32 small lifting surfaces. |
 | | Authorities differ over the date of the Breguet machine's first flight at Douai, 24 August and 19 September 1907 being quoted with equal assurance; on this occasion the aircraft rose to about 0.60m. |
