The 1947 Maury Island Incident: Analysis of FBI Investigative Records and the B-25 Bomber Crash

The Sighting over Puget Sound

On June 21, 1947, Harold Dahl, a harbor patrolman, was operating a salvage vessel near Maury Island in Puget Sound when he observed six large, donut-shaped objects in the sky. According to Dahl's testimony, one of the craft appeared to be in distress and discharged a significant amount of hot, metallic debris—described as 'slag'—which fell onto his boat, injuring his son and killing the family dog. This event occurred just three days before Kenneth Arnold’s famous sighting near Mt. Rainier, which launched the modern UFO era.

The First 'Man in Black'

The following morning, Dahl reported being visited by a man in a dark suit driving a new 1947 Buick. The individual allegedly recounted the events of the previous day in precise detail and warned Dahl not to speak of the incident, threatening that 'bad things' would happen if he did. This is widely considered by historians and researchers to be the first documented report of a 'Man in Black' in the context of UAP phenomena.

Military Investigation and Tragedy

Dahl contacted Fred Crisman, who claimed to have recovered more of the debris. The report eventually reached Intelligence Officers at Hamilton Field, California. Captain William L. Davidson and Lieutenant Frank M. Brown flew to Tacoma to investigate. After meeting with Dahl and Crisman and collecting samples of the debris, the officers departed in a B-25 bomber. Shortly after takeoff, the aircraft caught fire and crashed near Kelso, Washington, killing both Davidson and Brown.

FBI and Government Documentation

The crash triggered an intensive investigation by the FBI and the military. Declassified FBI teletypes from the era show that J. Edgar Hoover was personally briefed on the matter. While some investigators later labeled the event a hoax intended to generate publicity for a magazine, the official records in the FBI Vault detail the serious nature of the national security concerns at the time, including the possibility of Soviet interference or experimental domestic technology. The Maury Island incident remains a foundational case in the study of government UAP records.
