U2 or whatever
I seem to remember visiting OH detachment where we were shown around their aircraft in an exchange visit. They threw a sheet around the cockpit to prevent us stealing their "secrets".
When they visited us up the mountain (OLYMPUS- reason for the exchange), I remember we had a curtained area for communications and we placed a chair on top of a coffee table, shrouded it with a blanket, closed the curtains and frustrated the OH Crew and Support teams by refusing to disclose what was underneath the blanket after leaving the curtain slightly open.....childish I know but fun all the same.....
The most fun would be denying to Nicosia ATC (they used DME except for local ATC radars) that we had anything to do with that great rocket noise that most of Paphos and Limassol had heard Lol
