Back in the late 80s, one of the guys I raced go karts against was a pilot in the Air National Guard and they had a P-51 in the squadron.
Every late spring there is an Air Show at Reading (PA) Airport and he had the P-51 there. He said when he took it out, he would do a flyover the go kart track which is in Topton PA ( 15 or so air miles away )
He happened to do his flyover during intermission and was about 500' off the ground. VERY distinctive sound from the Merlin engine.
After he flew over, he gave more throttle and went into a climb. He was up a good distance when he "nosed over" and went into a dive. What an intimidating sound
He buzzed the track at probably 100' and the noise was intense. The poor ladies in the scoring booth had no idea what he was doing until it was over as he was behind them until he roared over them
