The only war story I ever heard about VR was from an old beefer who was instructing on the QHI course at cfs who said that he got it in a Whirlwind in Cyprus once and it took significant effort and height to get out of it. He was very high and in a hover (or was supposed to be) when he was distracted and then, when he noticed a v. high RoD, knee-jerked and pulled a load of pole.
He also used to tell the story of experiencing retreating blade stall in the same type (quite alarming by his account & I believe him). I used to think that he perhaps wasn't the best helo puke in the world but, as he was also an ex Lightning jock, he must have had something about him. Can't remember his name but only his nickname!
