It's only relatively recently (1970s) that a mil call sign was allowed in civil airspace- when we were operating the Hueys from Amberley, we used Albatross XX when in mil airspace, but had to use a civil call sign in civvy airspace. One of the birds was VH-HEN, and when asked to squawk, the usual response was "Buck buck bacawwwwww!!"
The Hercules were Juliet Lima whatever, and one of Frank's best stuff ups (only RAAFies would know who Frank was) was on departure out of Richmond in VH-JLP, and his departure call to Syd Radar was (in Frank's very imitable gentlemanly style) "Sydney, this is Juliet Lima uhhhhhhhhhh........(forgets what Papa is)...Pineapple!"
