UFO Investigation — Tillamook, Oregon, March 1967

This document is a comprehensive investigation report regarding a series of Unidentified Aerial Phenomena (UAP) sightings that occurred in the vicinity of Tillamook, Oregon, between March 11 and March 13, 1967. The sightings involved multiple witnesses, including local law enforcement officers and a reserve deputy sheriff, who reported observing red, white, and green blinking lights that appeared four to five times larger than stars. These objects were described as hovering and moving in ways that suggested helicopter-like flight characteristics, though subsequent checks with military and private aviation sources confirmed no such aircraft were operating in the area at the time. The 698th Radar Squadron at Mt. Hebo also tracked the objects, reporting a 'solid metallic' return on their scopes. The radar data showed highly unusual movement, including rapid distance changes of nine miles within a single minute, implying extreme acceleration and deceleration. Despite the radar data, the Foreign Technology Division (FTD) concluded that the radar returns were likely 'false targets' caused by temperature inversions, which were confirmed to be present during the period. The report acknowledges that the investigation was inconclusive and that the visual sightings remained unidentified. The investigating officer, 1st Lt. Frank W. Bean, noted that the observed flight characteristics were inconsistent with known aircraft. The file includes witness statements, radar logs, weather data, and correspondence between the 325th Fighter Wing and the FTD, as well as a recommendation that the University of Colorado Physics Department, then conducting a study on UFOs, might provide a logical explanation for the events.
