Mr shack and A2, I did not challenge Mr crun. I have followed his contributions for years now and if he says something is so I accept it as so unless I have very good evidence to the contrary, which so far I have yet to find.
A year or two ago I was chatting with an ex-RCAF pilot of fairly recent vintage, and the topic of attrition came up. I was astonished to learn that in his time he had known two pilots who were killed.
I once idly made a list of pilots who had to my knowledge gone to glory, 1953 to 1957, in the RAF and FAA, all in conditions of peace. I stopped the depressing task at 34.
As I was being strapped into a hot pursuit ship, lukewarm anyway, at one of Mr shack's FTS during his years, the cheery airman offered the pensee: "About time again, Sir!". He and his mates, so he told me, reckoned on at least "one" per ten weeks, and we were now at week 9.
I have never seen the statistics on the Vampire 5 and the Venom, but I'd like to.
