Helicopters started out as a psyop in the Vietnam war. They can’t actually fly, and couldn’t do so especially in the 60s, but the USA used clever propaganda movies to convince the commies that they did. Then, some retards actually started building them, first also as fakes (being pulled by cords on plains), but recently they tried to make them actually work on their own, which is why they crash. 
Google Stepok River cover up. In 1975, the viets actually found one of the fake helicopters and even tried to tell the American public

This is the dumbest shit I've ever heard. I've been on helicopters before, they're definitely real and there aren't any magic invisible airplanes pulling them. Read a fucking book you retarded faggot.
