Maury Island Incident: A 1947 UFO Hoax that Shaped Postwar Lore

To the point

The 1947 Maury Island incident involved Fred Crisman and Harold Dahl claiming six doughnut-shaped flying objects over the water with debris on their boat and a warning not to talk, an investigation led by Kenneth Arnold and others, and the FBI and Air Force later deeming it a hoax, yet it remains an enduring part of UFO lore and local commemorations.

Fred Crisman and Harold Dahl claimed in 1947 that six doughnut-shaped flying objects over Maury Island released debris that rained on their boat and that a man in a dark suit warned them not to talk; the tale drew in Kenneth Arnold, Raymond A. Palmer, and military investigators who collected fragments before Lt. Frank Brown and Captain William L. Davidson were killed in a B-25 crash near Kelso, Washington, the FBI concluding it was a hoax and Air Force supervisor Edward J. Ruppelt calling it "the dirtiest hoax in UFO history," yet the episode continues to echo in culture and commemorations such as a 2017 Washington State Senate acknowledgment and a 2024 Des Moines "Men in Black Birthday Bash."
