LangleyB: As I recall, Tim Thorn went out after his SASO RAFG time to run security for De Beers.
Quite unrelated, I went through Nav training with a chap who had only ever wanted to be a Provost officer but OASC had pointed him along the aircrew path. He kept just squeezing through each part of the Course until about a month from the end when the System finally accepted that perhaps he'd been right all along, and sent him for Provost training. Last I saw of him years later was as a Wg Cdr.
