Project 10073 Record Card — Dallas, Texas, 4 September 1956

This document is a Project 10073 record card detailing an Unidentified Aerial Phenomena (UAP) sighting that occurred on September 4, 1956, in the vicinity of Dallas and Grand Prairie, Texas. The primary witness, identified as AD/2 Terry, a tower operator with 13 years of experience as an aircraft mechanic and two years of experience in tower operations, observed the object for approximately 23 minutes. The object was described as star-shaped, roughly the size of a dime, and exhibited a color change from white to red. It remained stationary at an altitude of 20,000 feet for 20 minutes before moving west at an estimated speed of 200 knots. The report notes that there was no sound associated with the object. The investigating authorities at the Air Technical Intelligence Center (ATIC) evaluated the sighting, noting that the object's movement against prevailing winds effectively ruled out the possibility of it being a balloon. While the initial 20-minute stationary period suggested the possibility of an astronomical body, the significant lateral movement observed—specifically the change in azimuth from 080 degrees to 330 degrees—led the investigators to conclude that the object remained unidentified. The document includes a teletype message confirming the details of the report, which was distributed to various military commands, including the 745th ACWRON at Duncanville, Texas, and the 33rd Air Division at Oklahoma City Air Force Base. The weather conditions at the time were reported as clear with good visibility, and no radar contact was made.
