Heard over Oklahoma City approach frequency on a busy day:
Approach:
"American One Twenty-Three, descend pilot's discretion. Maintain 6,000."
American 123[after a long pause]:
"Oak City, American One Twenty-Three. Did you call us?"
Approach:
"American One Twenty-Three, descend pilot's discretion. Maintain 6,000."
American 123:
"Say again."
Approach[getting a bit hot]:
"American One Twenty-Three: Descend and maintain 6,000. Pilot's discretion, co-pilot's discretion it really doesn't matter to me!"
