We once had a navigator known as 'Seagull' - because you had to throw things at him in order to encourage him to fly....
The only time I can recall being frightened in an aeroplane was when the QFI with whom I was flying in a JP decided without any warning to demonstrate rolling inverted and pulling over hills in the Yorkshire Dales at considerably less than 250' a.g.l. "That's what TSR-2 was designed to do!", he said afterwards - perpetuating that myth.
He later killed himself in a Jaguar, I gather....
