My first introduction to helicopters was straight from school in 1963 when I joined the Met Office and reported for work at the helicopter training station at Tern Hill. I was only there two weeks before I was moved to Bracknell which was to prove the end of my Civil Service career... (for about 25ish years.)
I learned two things about helicopters. When they're close by a building, everything rattles from the noise ... and I mean EVERYTHING !!! Sometimes their landings are impressive, at other times they land like Zebedee on steroids.
And no, I've never flown on one. I have a lot of faith in gravity. (Many people think saying
'gravity is only a theory' makes themselves look clever. I've yet to meet one who would accept my request to step off a high cliff to challenge the
'theory.')
