This used to be a regular feature, not sure why we let it drop.
An RAF Typhoon pilot was flying a mission over Benghazi when, to his surprise, he spotted two flying carpets in his vicinity. Deciding they looked pretty hostile, he shot them down. On his return to Gioia del Colle, the base commander was furious with him:
"those were Allied carpets !"
Hmmm, perhaps that's why we dropped the Friday joke ...
