Helicopters - that's another one which I forgot about.I was a Naval cadet (CCF), yes we did stuff that would give people heart failure nowadays. We did similar night exercises with military grade thunderflashes, got to fire a Bofors 40mm which was fun, also winched up into a Wessex helicopter with just a strop under my arms. I remember the safety briefing for that - "don't lift your arms up or you'll fall out of it and die"
Sometimes we were flown in them, and if they knew it was your first time, they stalled the engine to scare the shit out of you - it worked to be fair
