What was reported
Harbor patrolman Harold Dahl and his associate Fred Crisman claimed that six doughnut-shaped craft hovered over Dahl's boat and one dropped slag-like debris that killed a dog and injured his son. Kenneth Arnold was brought in to investigate, and two Army Air Forces intelligence officers who took custody of fragments died when their B-25 crashed on the return flight, which fed later cover-up stories. The FBI file released through PURSUE records the investigators' finding that the story was false, Dahl's statement that he would call it a hoax if questioned, and a reporter calling it a complete fabrication. Edward Ruppelt later called it the dirtiest hoax in UFO history.
What officials concluded

The section's central content is the FBI's own investigation of the Maury Island incident (Tacoma, WA, June-August 1947): Harold Dahl and Fred Crisman's story of disc fragments falling on Dahl's boat, told to Kenneth Arnold and to two Army Air Forces intelligence officers who died in a B-25 crash hours after taking custody of the fragments. The file records that an Associated Press wireman found Dahl's own wife pushing him to admit 'the entire story was a plain fantasy' and that a Boise reporter independently called it 'a complete fabrication.' The section also carries the formal FBI-AAF correspondence on cooperation terms, including an Air Defense Command memo limiting the Bureau's role to discs found on the ground, and a Bureau memo dated near the end of the section recording that the FBI discontinued its flying-disc investigative activity effective immediately per Bureau Bulletin No. 42, referring all future reports to the Air Forces.
