I heard it on the radio...

Flight numbers changed to protect the guilty... :-)

St. Louis approach to United: "United 123 best forward speed to the marker, you're number one."

United 123 (male voice): "Roger, balls to the wall."

St. Louis approach to American: "American 4321, you're number two behind a United 737, follow him, cleared visual, best forward speed."

American 4321 (female voice): "Well I can't do balls to the wall but I can do wide open."

-Radio silence-

Unidentified Pilot (male voice): "Is American hiring?"
