Callsigns
All military formation callsigns for use in the U.K. had to be from an approved list which naturally was plundered by the pointy folk before slower formations got a look in. Startrek, Mallard and Snapdragon really didn't convey the idea of a small village with wings on using up several miles of airspace thundering across the U. K. at low level but that was our fate in S.T.S.
Overseas the choice was unfettered. Slipper 1 and Giver 1 raised sniggers in Southern California and the end of day call to the tower of "Elvis has left the theatre" was most righteous.
