I trained on the penultimate RAF Whirlwind basic course. It was actually a very large aircraft for a basic trainer, a bit like flying a small bungalow from the Dormer window. But it was a good lead in to the Wessex 5 as an advanced trainer!
For years I flew almost every working day over a dilapidated Whirlwind located in a small clearing in a wood, I think it was a paintball adventure place. Much later I discovered it was actually the very airframe in which I’d carried out my first helicopter solo and my first night solo. By then it had sadly gone, probably for scrap.
