June 21, 1947 · Puget Sound, Washington, United States
Harold Dahl reported seeing multiple disc-like objects over Puget Sound, one of which allegedly shed metallic slag-like debris that injured his son and killed a dog. The case quickly drew attention from early civilian investigators.
It is one of the earliest postwar U.S. disc cases and became entangled in controversy after military intelligence involvement and the fatal crash of two Army Air Forces officers returning from the region.
Army Air Forces Counterintelligence and FBI files treated the case as suspicious and likely fabricated in parts.
Documentation confirms official concern, but evidence quality and witness reliability issues remained severe.
Most historians classify Maury Island primarily as a hoax or embellished event.
Some researchers continue to argue that official sensitivity and associated deaths justify retaining it in early UAP chronologies.
The incident illustrates how quickly media, intelligence, and folklore converged in the 1947 flying disc era.
It remains a methodological caution case in UFO historical research.
