Royal Air Force pilot Alan Pollock was disappointed that no aerial displays had been planned to mark the RAF’s semicentennial in April 1968. So he performed one himself: He took off in an unauthorized Hawker Hunter from RAF Tangmere in Sussex and flew to London, where he circled the Houses of Parliament three times, dipped his wings over the RAF Memorial, and then found himself facing an unexpected landmark:
Until this very instant I’d had absolutely no idea that, of course, Tower Bridge would be there. It was easy enough to fly over it, but the idea of flying through the spans suddenly struck me. I had just ten seconds to grapple with the seductive proposition which few ground attack pilots of any nationality could have resisted. My brain started racing to reach a decision. Years of fast low-level strike flying made the decision simple.
He flew between the spans, becoming the first pilot to do so in a jet aircraft. He buzzed three more airfields before returning to his base, where he was promptly arrested. But rather than face a court-martial he was quietly invalided out of the RAF on medical grounds — the government didn’t want to bring any more attention to the stunt.
