I would suggest that the name Staplefordheli might be a clue to this thread. Possibility is that he is a helicopter pilot/fan and may be one of those people who are of the opinion that the air is for fling wings only. Only speculation on my part mind you.
I know that at ten years old I would have been mesmerised as opposed to terrified by someone "overhead" doing aerobatics. Not only at ten, a few years ago while working in Loughborough I returned to the hotel in the afternoon and as I parked the car I noticed someone close to the overhead performing aeros and I stood so long watching that some of the hotel staff came out to see if I had found something wrong on the roof. Can't help it.
