Here are a couple:
radar: Spitfire G-xx squawk 1234
spit: Sorry sir, -ve transponder.
radar (puzzled, watching 7000 leaping across screen exactly where spit says he is, at spit speeds & same level): Are you sure you don't have a transponder? If not, there's traffic very close by, same height & speed.
Spit: hang on, I'll look...(lenghthy pause).
Spit (very surprised): Bloody hell, I've found one! What was that squawk again?
Same place, different day.
radar: G-xx report position
C150: G-xx is about 5 miles north of the A14.
(For those of you scratching your heads, the A14 runs E-W from Birmingham to Felixtowe)
