Whenever P-51 Mustangs are shown in flight, they are accompanied by their trademark gun port whistle, even while in level flight. In actuality, the whistle only occurs during high G turns and climbs, when the angle of attack on the gun ports is sufficient to create the sound. Some attribute this noise to the supercharger on the Rolls engine, however in fact it is created by the gun ports, and as such demilitarized P-51s with their gun ports removed do not make the sound.
