Brilliant F4 story, it reminds of an airshow flypast back in eighties here in Ireland. It was held at a horse racing track near Dublin. It was well supported by the USAFE who sent F15s, F111s and a Jolly Green and an RF4C. I was on the grandstand overlooking the finish line and commentary box. After a couple of ordinary passes high and low speed. It culminated in a high alpha low speed full afterburner, very low pass. I was looking down on it. As it passed the commentary box they occupants visibly ducked. Afterwards the commentator told us they had felt the heat of the burner as the Phantom passed them. I'd well believe it. It wasn't the lowest every pass I saw at an airshow at that racetrack. But it was the lowest military jet. I think I have a photo somewhere. Must dig it out.
