The Mach Loop – low-level training areas for fast jet aircraft (en.wikipedia.org)

That was normal at the time. At least for the allied forces. Notice how i didn't mention F-104G Starfighter? That's because they didn't do that, at least not there. One DID "buzz" me with an almost deafening sonic boom, really solid pressure wave when bicyling in some forest somewhere else in maybe 1984. Suddenly, out of nowhere, and then gone again, except for the roaring of the air for maybe a minute after. Also at that time: looking out of the window at home, again on a hillside, a F-111 roaring down the little valley from behind the house, hopping over some ridge, becoming visible again, and rising almost vertically to the top of the https://en.wikipedia.org/wiki/Drachenfels_(Siebengebirge) over the Rhine, waggling its wings, then nosediving again to the right to vanish into the https://en.wikipedia.org/wiki/Siebengebirge All in what seemed to be a minute and VERY LOUD! I later reconstructed the flight path on a map, which showed it going over the Russian embassy and consulate first, then over the American one. As to why the F104 was supersonic while so low, i have no clue. Maybe a near crash? Its direction pointed to https://en.wikipedia.org/wiki/N%C3%B6rvenich_Air_Base roughly. As for school? No problem, had effortless Ones or Twos/A-Grade/B-Grade. It was mostly boring, really.
