Wasn't that Gnat accident the reason for ALWAYS pre-fixing numbers with formation callsigns? No "You're on fire" being confused with "Four, on fire" etc.
A Vixen CO confirmed to me in about 1966 that the Vixen loss rate was indeed worse than the F104 rate. But I had a super trip as a CCF Cpl in the coal-hole of a Vixen - only the RN could pull such strings, the RAF wouldn't even give me a Chipmunk AEF trip!
I understand that Pusser banned the use of the words "Oh $hit" in the air after some Vixen looker confused them with the command "Eject!".......?
