Project 10073 Record Card — Portland, Oregon, 30 July 1955

On July 30, 1955, at 2243Z, a sighting of an unidentified aerial object was reported in Portland, Oregon. The report, filed by the 635th ACWRON, details a sighting by a witness identified as G.W. Thomas, a housewife, and A/1C T.N. Taylor of the 4770th Detachment 3, Ground Observer Corps (GOC). The object was described as round, silver, and silent. It remained stationary for approximately three minutes before disappearing over a hill. The weather conditions at the time were reported as clear with no wind. The incident was documented on a Project 10073 record card and an AISS-UFOB-254-55 index card. Official conclusions regarding the nature of the object were mixed; the initial record card labeled it a 'Probable a/c Sighting,' while the subsequent index card noted that the object's stationary behavior suggested the possibility of a balloon. The report explicitly states that no formal investigation was authorized. The documentation includes a teletype message confirming the report was submitted in accordance with AFR 205-2, paragraph 7.1, and notes that no AF Form 112 would be submitted.
