(Capcom's primary storyline)
"This is 73-Bird----for rescue.-----heading east----River. Touchdown at R.P.D.-----minutes.I repeat, touchdown----"
— 73 Bird last words to radio.
"73 Bird" was the callsign of a Raccoon Police Department helicopter pilot. During the latter stages of the Raccoon City Destruction Incident, he made an attempt to fly back to the Raccoon Police Station from the other side of the Circular River.
He later crashes his helicopter into the side of the police station on the 2nd floor, barring entry through the hallway. It is unknown what caused him to crash, but with him failing to wake up it can be assumed he was never mutated from infection and indeed died on impact.
