Coffman,
your request is stirring some of my remaining memory cells into action again. I will drip feed them as it were.
Once Op Corporate was over we were bringing back lots of kit, much of it Argentinian. I remember radar cabins and various bits of comms kit.
One day the load turned out to be an a/c load of bombs on pallets. They looked very secondhand indeed. Chalked on each one was the inscription' X-ray checked fit to return to UK one flight only' Ummm ! I do not know whether they were ours or Argentinian or why it was necessary to bring them to the UK.
Someone somewhere was going to have 'fun' with them.
