Had a mob of cattle mustered up, and driving them to the yards on our leased Forestry block west of the Mary River, back in about '74/'75 or so, (not long after we finally got ours, and the guys were training hard down low in case they had to drop a bomb in anger). Anyway, we were under one of the Low Jet Routes, (probably the one from Kilkivan to about Childers before they did the 'abrupt vertical manoeuvring' - as it was described on the Notams). When the first one came over at what felt like tree-top height, the cattle spooked and scattered - of course, - so we had to spend a few more hours gathering them out of hiding again. Had a few choice words at the time, - but forgave them, of course.. fascinated.
