To set the scene this was at Heathrow and where the British Airways Flying Club used to get their planes repainted in the same BA livery as the big jets. Waiting to take off was a British Airways 747, then a BritishAirwaysFlyingClub Piper Warrior and following that an American Airlines Jet.
American Airlines pilot watching whats ahead of him and in a very thick American accent:
"Hey Speedybird, looks like you've given birth!"
This is another great story I was told by a BA Captain.
Unknown aircraft: "!!!!!"
ATC: "Who was that?? Identify yourself"
Long pause....
American Airlines pilot: "We didn't say !!!!"
BA Pilot: "We didn't say !!!!"
Air Canada Pilot: "We didn't say !!!!"
Followed by just about every other pilot on frequency!
