As an aside.....
Whilst on exercise `somewhere` with the Jags in the 80s we were invited to view the local threat museum one `down` day. There had been rumours of complete eastern bloc airframes to see. We were so dissapointed seeing only 40s technology soviet radar and AAA, plus a couple of WWII tanks, that we asked the very smart and heavily armed security trooper where all the `jets` were.... His polite reply was along the lines of "Sir - there are no aircraft here, SIR!" This was shortly followed by a crisp salute and the words "But......If you take the second door on the right on your way out, you will see....erm...no jets" We then spent several happy hours clambering over ....erm...nothing...All very interesting.
