A Pan Am 727 flight, waiting for start clearance in Munich, overheard the following:
Lufthansa (in German): “Ground, what is our start clearance time?”
Ground (in English): “If you want an answer you must speak in English.”
Lufthansa (in English): “I am a German, flying a German airplane, in Germany Why must I speak English?”
Unknown voice from another plane (in a beautiful British accent): “Because you lost the bloody war!”
