Seeing as we have mentioned "Vulcan" and "USA" in the same post I'll chuck out the story of one of these little air defence exercises when a Septic fighter pilot came up behind a Vulcan and went "bang bang you're dead" over the radio. Vulcan pilot replied "Damn bad show what" and the two Buccaneers that had been flying under the Vulcan darted off in different directions leaving the fighter pilot somewhat bemused...
I used to work with a bloke who worked in the special weapons storage in RAFG, nice guy with some cracking war stories. He once let slip that he had literally "hugged his bomb" one day and found it to be slightly warm to the touch.
Taking of those sort of weapons, I had some CND type bloke button me in a pub one night after he found out I was in the air farce. He kept pushing me to admit we have that sort of thing where I worked but I was not going to admit anything (I knew for a fact we didn't but it was fun winding him up). At the end of the night he's got to the stage of slagging me off to try and make me give something away, so he said "You've probably never even seen one of the these weapons or been anywhere close to them". I'd just finished my pint and was getting my coat on when I turned to him and said "I have been within ten feet of one of the most advanced nuclear weapons in the world". He suddenly started to smile as if he'd won and asked "Was that at RAF XXXX then"? and I replied "Nope, it was in the middle lane of the M25 as I overtook this funny looking green lorry......"
