To issue a VSA I need to hear "visual" as in "can maintain continuous visual reference to the ground or water etc..." "Visual on top" is so frustrating - can't give you anything based on that cobber!
But USA military pilots definitely get my vote for bizarre RT:
"Comin' at ya, abeam the numbers, good gear, goin' nowhere" (Southern drawl)
Heard it 14 years ago on my first TWR rating, can still hear it plain as anything. For a minute there, I wasn't even sure it was English, then my supervisor managed to stop laughing long enough to say "base, 3 greens, full stop". Guess I haven't watched Top Gun enough.....
