This thread has brought back some memories..... A certain Jaguar squadron were going to do an 8-ship and yes it did happen and wasn't a hysterical fantasy!
Their sortie callsign would be Boxer 1-8 (oops, have I just given away the identity of the miscreant Sqn?), but they would be made up of 2, 4-ships, Turbo 1-4 and Havoc 1-4 (yes I know that was a 54 callsign but google has unusually not been kind enough to prompt my memory).
Unfortunately, this was not confusing enough, because Turbo 1&2 would be Boxer 3&4, whilst Havoc 1&2 would be Boxer 1&2, Turbo 3&4 would be Bozer 7&8 etc etc. Can you guess what happened next readers?
