When I was a young tacker at high school down in NSW, the school that I went to had a former student as an F-111 pilot. For a number of years, maybe 3-4 times a year you'd be sitting there bored out of your brains, then the rumble would start, followed shortly after by one, sometimes 2 F-111's very low and very fast over the school, swing it around over town with wings swept and up on 90 degrees, then go vertical and head back to Amberley.
I found out years later that, as with most places in the country, they were doing practice bomb runs on the school.
We also lived out of town in a long valley that also attracted a number of the boys doing practice TFR runs at bugger all altitude. An awesome sight that was sad to see go.
