Met John many times at Farnborough.
It always amazed how, with only one arm and carrying a big wad of notes for his commentary, he climbed the vertical ladder to the commentators box.

He was also a keen photographer, and beat me to the cover of a magazine in the 70's with a formation shot of Cosmic Winds at one of the race meetings. We organised the photo flight rather rapidly, talking a relatively (I think) inexperienced pilot who happened to be handy with C172 into flying the photographers, John and I, with John instructing him to ""fly a nice smooth l/h bank & don't look at the others." First ever formation shot of 3 Cosmic Winds?
