My brother was a 75 squadron leader (F18's) until early this year. Mum and dad have a farm 30 minutes outside of Bathurst. A few years back he was returning from Canberra, and used the farm as a Nav point, putting on a 10 minute aerobatics display for dad sitting on the front verandah. Sat it on its tail and disappeared into the clouds at the end. I think they used to run at about $7000 and hour flying costs - that's where our taxes go fellas
