Maury Island incident — Harbor patrolman Harold Dahl reported six doughnut-shaped objects over Puget Sound, one of which dropped hot metal debris. The case became entangled with early Men in Black lore.
On June 21, 1947, three days before Kenneth Arnold's famous "flying saucer" report over Mount Rainier, harbour patrolman Harold Dahl reported seeing six donut-shaped craft over Maury Island near Tacoma, Washington, one of which allegedly dropped molten metallic slag onto his boat, injuring his son and killing the family dog. The case is widely considered the inaugural UFO conspiracy story and is intertwined with the death of two military investigators in a B-25 crash. 【Background】 Dahl operated a small salvage boat in Puget Sound, working scrap timber and other debris from the water. Maury Island lies just southeast of Vashon Island in the inland waters near Tacoma. The reported encounter happened on a clear early-summer morning. 【The Encounter】 Dahl said the six donut-shaped craft hovered above his boat, with one descending and ejecting a shower of hot metallic slag that struck the boat, burning his son and killing the family dog. He claimed to have collected slag fragments. Later he reported being visited by a "Man in Black" who warned him to keep silent — one of the earliest such reports in UFO literature. 【Investigation】 Two US Army Air Forces investigators, Captain William Davidson and First Lieutenant Frank Brown, flew from Hamilton Field to interview Dahl. On the return flight from McChord Field, their B-25 bomber caught fire and crashed near Kelso, Washington, killing both officers; two other crew members parachuted to safety. The slag fragments Dahl provided were determined by the Air Force to be ordinary smelter slag of terrestrial origin. Kenneth Arnold himself interviewed Dahl as a journalist for FATE magazine and ultimately concluded the case was a hoax. 【Modern Assessment】 Maury Island is now generally regarded as an early flying-saucer hoax, but the combination of an early "Man in Black" report and the contemporaneous deaths of two Air Force investigators gave the case lasting influence on UFO conspiracy literature. The case is detailed in Kenneth Arnold's own book "The Coming of the Saucers" (1952), where Arnold ultimately rejected Dahl's account while acknowledging that the deaths of the Air Force officers had genuinely complicated the public record.
