One Sunday afternoon some years back I was circuit bashing at Lands End with my instructor when I was doing my PPL. On returning to the clubhouse we were met with much hilarity. A local lady had rung in to complain that while she and her (female) friend had been sunbathing in their underwear in the garden, the same aircraft, G-OCPC, had flown directly over them three times. We were naturally a bit miffed that we hadn't spotted the ladies, but at least I was able to point out to my instructor that I had obviously been flying accurate circuits.
