The Maury Island incident (1947)
Cases, documents & milestones
On 21 June 1947 Harold Dahl claimed to have seen six doughnut-shaped craft over Puget Sound, one of them dropping debris. Kenneth Arnold investigated on the spot. Two Army Air Forces intelligence officers died when their bomber crashed on the way back. The FBI investigation concluded it was a hoax, but the affair remained famous, notably for its mention of a man in black.
