One of our (late) family friends was a pilot named Chris Braund (of the famous stammer) who bought two P-51 Mustangs for 50 Pounds each in the early 60s. He would fly them to air shows and do flour bombing displays and beatups.
The story, probably much modified with retelling, was that he wanted to overfly Sydney Airport, but the Air Tragic Controllers told him to do an orbit at the Harbour Bridge.
So he did - a vertical orbit, passing under the bridge. "They-they-they d-d-didn't say it had to be h-h-h-horizontal!"
