это же Pitts Sky Car, 1928 год... его все знают.
в книге сурового сибирского физика Павла Полуяна он приводится как одно из доказательств земного происхождения летающих тарелок. По версии ПП на них летают люди в черном из КГБ и ЦРУ.

Pitts Sky Car film clips. Didn't fly but it sure cleared the area of debris.
Sky Car 1928 = 1pOH; 90hp Curtiss OX-5. The best thing that could be said about this machine is that it was a nice try. It appears to be the first helicopter with vibration designed into it (US patent #1,602,778). Each blade of the 60-blade rotor had a full-radius vane attached to it that was free to flap about its radial hinge. Rotation caused the drooping vanes to swing out, closing the space between blades and forming a solid rotor disk, the point being that the rotor was forced by the engine to reciprocate up and down. When the rotor went up the vanes were flung open, allowing the air to pass between the blades; when it then moved downwards, the vanes closed and a good portion of air was thrown downwards, thus supposedly creating a lifting force. Motion pictures recorded a flight attempt in which it is seen pathetically jumping up and down like an irate washing machine, but it is dubious if this was caused by downwash—after all, when one heavy part of a machine is forced down some other part must go up, according to the laws of mechanics.
