Since the content of the pilot's radio call is of such consequence, I'd like to point out that the initial reporting call on the full version of the tape includes the full (if rushed) callsign of "Acey 5912". "Acey" being the callsign of Atlantic Southeast Airlines (ASA), now a subsidiary of ExpressJet.
I would also point out that the controller has come under increased scrutiny because this was the same airport that sent emergency responders in the wrong direction last time there was an accident on the runway.
