Welsh rhetoric
I once had a Welsh instructor, whom I believe hailed from Swansea. He had that thoroughly Welsh penchant for rhetoric and, incidentally the loudest voice I had ever heard.
On one occasion early in my PPL course, flying an Auster, we were proceeding along one of Barton aerodrome's rough grass runways in a series of violent porpoising bounces when above the din of the unsilenced engine (we didn't wear headphones in those days - no radio) I heard him bawl 'you're like a b****y navvy with a steamroller'!
One of his favourite tricks was when you were trying to land the Auster on a hot day and she had got into ground effect and was floating and floating and floating just above the runway. He'd suddenly start singing 'Jesus wants me for a sunbeam' at the top of his voice.
