Project Blue Book Record Card — The Dalles, Oregon, 25 July 1952

This document is a teletype report concerning an aerial sighting that occurred on July 25, 1952, near The Dalles, Oregon. The primary witness, identified as an Assistant Chief Observer with the Ground Observer Corps, observed a transparent white, balloon-shaped object from a position atop Klickitat Mountain. The witness, utilizing high-powered glasses, reported that the object remained stationary for approximately four minutes before moving upward. During the observation, the object appeared to 'open up,' releasing a secondary object that circled the primary craft before disappearing. The primary object subsequently disintegrated, leaving small streaks of vapor trails, and four parachutes were observed falling on the south side of Mount Adams. The report notes that the observer possessed an instrument to measure altitude but could not definitively determine if the object was at 15,000 feet, 71,000 feet, or 7,100 feet. The document also references a GMI Flight 797 that was in the area at 1847Z, noting that a balloon had been dropped in the vicinity. The report concludes with a statement that there was no aircraft activity and no further information was available at the headquarters level.
