Coincidence?
At RAAF Pearce in the late 70s our CO was Wg Cdr Bob "Bobo" Greenwood.
A local real estate developer had bought a tract of land under downwind for R/W 18, and one Friday he came onto the base and told the CO to avoid his land over the weekend, as there was a big land sale going on.
Normally, 2FTS didn't operate on weekends, so the developer must have been feeling confident. But Bobo called us all onto duty, and the end of every sortie had to include a low level circuit in the Maccherschmidt to make as much noise as possible on downwind. So, we did.
Didn't make a difference, the land was sold, and the new owners started bleating about the noise straight away.
