I can relate to Rusty sparrows post. I learnt first time around in mid 70's and did some time with a NZ seaman who instructed between voyages. He had me descending and turning and kept pushing me turn tighter when all of a sudden over she went the other way and into a nice spin. Very powerful learning moment, especially as he hadn't warned me what we were about. Great character who once on PFL said right mags off keys out the window. Intended to imply concentrate on landing from that point. However he reached across my knees to the keys and I saw a flicker of silver being thrown out the window. Turned out to be silver paper but really focused me at the time until I realised the engine was still running.What a larf.
