I was on operations at Tumby in early 70's. Interesting reading your comments.
Yes, we changed our call sign when we lumbered along the roads to various parts of the UK. (We were nicknamed The Flintstones). I think we were the only one of its kind left in UK at the time.
From Vulcans to B52's ... And some speedy fighters ....And some propeller types carrying out training flights at horrible slow speeds ... You were all sometimes hard to pinpoint in the skies around. No help from radar stations, just a beam in the sky.
Fun times were when the evening silence was broken by the radio, patched through to the ping pong table, crackling into life with some high flying, globe trotting B52 checking in to see if they could do a run. Always the calm, relaxed and polite drawl. Unlike the curt, short, no jokes raf pilots (well ... Not all :-) )
Lighter times with USAF UK based fighters were the crates of Budweiser they would send up "maybe in hope of some better scores".
Lots of stories ... But I guess they have to stay in my head ....
Go on Chisel...would love to extract those stories from your head!
