It was with some amusement that we (a Delta 777) listened to the following exchange between Frankfurt ground control and a British Airways 747 (callsign Speedbird 206) after landing:
Speedbird 206: "Good morning Frankfurt, we cleared off the active runway."
Ground: "Guten morgen! You vill taxi to your gate!"
The British Airways 747 pulled onto the main taxiway and stopped.
Ground: "Speedbird, do you not know vare you are going?"
Speedbird 206: "Stand by, ground, I'm looking up the gate location now."
Ground (with impatience): "Speedbird 206, haff you never flown to Frankfurt before?"
Speedbird 206 (coolly): "Yes, in 1944. But I didn't stop."
