Especially at low speed, such as during takeoff, while hovering, and while landing, helicopters are famously difficult (impossible) to control for someone with no experience. Is there a documented instance of any person ever successfully taking off, hovering, and landing a helicopter with no actual flight experience? It must all be in one flight, first time--someone teaching themselves over multiple short flights / hours does not count. Simulator use is OK and does not count as actual flight experience for the purposes of this question.
Yes, Eric "Winkle" Brown took delivery of a Sikorsky R-4 and flew it after reading the flight manual and getting a briefing from a USAF Sergeant. He had no experience or training in helicopters. He wrote about it in "Wings of the Weird and Wonderful".
