I wasn't there at the time but am relating this story as it was told to me:
Back in the day when a girl military pilot was a real novelty, a certain red-haired big mustachioed RAAF helicopter pilot who shares a name with a kind of beer made famous by 'The Simpsons' (but who shall remain nameless), was on an exercise involving Australian and Kiwi helicopters.
The Kiwis had a female pilot nicknamed 'BC' for some reason. Seeing this name on the tasking board but blissfully unaware that it referred to the girl, our hero was heard loudly conjecturing whether the initials stood for 'Big C***'.
Imagine his red-faced back-pedalling when he was overheard by said pilot...
Arrrf!
