Boots and 'light Aircraft'
In the Tiger Club (Redhill Days) all new members HAD to check out to solo standard in a Tiger Moth as the initial entrance to the 'sweet shop'.
Came the day when they decided that having a putter around in a Turbulent looked like being fun, and they would 'clump' over in the classic WW2 boots and Irvin Jacket.
I would get them to lift the Turb by the tail thereby demonstrating how light it was, and easy to nose over if not careful. This then rather made the case for removing the boots and flying in socks having of course also removed the Irvin Jacket so they could actually fit in.
Finger and thumb only on the stick and only 'feel' it to control then it was off to discover another 'realm' of aviation unknown to most.
