I remember one day I was loafing in the crew room when the phone rang and our squadron Eng O asked if any aircrew with nothing better to do would come and lend a hand washing down one of our aircraft (Victor K1). There was a general muttering of the "on your bike" variety, and I dont think anyone took him up on the offer. Even 45 years later I still feel a bit guilty about that - it wouldn't have killed me and it might even have been interesting. Sorry chaps!
