On 3 July 1938, the LNER locomotive Mallard hurtled down Stoke Bank in Lincolnshire and hit 125.88 miles per hour, a world record for steam that has never been broken. The achievement came at a cost: the engine’s middle big-end bearing overheated, and Mallard limped to Peterborough for repairs. She survived, worked for another 25 years, and now rests at the National Railway Museum in York. Fifty years after Pickett’s Charge, Confederate and Union veterans returned to Gettysburg for the Great Reunion of 1913. On 3 July, they walked the same ground and shook hands across the wall at Cemetery Ridge, a moment of reconciliation captured in photographs and memory, though the wider context of racial injustice complicates its legacy. In 1988, USS Vincennes shot down Iran Air Flight 655 over the Persian Gulf, killing all 290 people on board, including 66 children. The civilian Airbus had been misidentified as a military threat. The United States expressed regret but never formally apologised. And in 1973, David Bowie killed Ziggy Stardust on stage at the Hammersmith Odeon, ending his most famous alter ego without warning the band or the audience. Clara Vale examines a day of speed, memory, tragedy, and theatrical self-destruction.
