Project 10073 Record Card and Air Intelligence Information Report — 26 September 1957

This document consists of a Project 10073 Record Card and an Air Intelligence Information Report regarding a UFO sighting on 26 September 1957 in Washington, D.C. Three civilian witnesses reported seeing a long, rectangular, gray object, described as being the size of a blimp, moving to the north. The observation lasted for approximately five minutes. The witnesses were traveling by car from Eastover, Maryland, toward the vicinity of Nichols Avenue and Chesapeake Street in Washington, D.C. The weather was reported as mostly fair with high, thin, broken clouds above 30,000 feet and visibility of seven miles. The official conclusion reached by the Air Technical Intelligence Center (ATIC) and the reporting officer, Major James E. Geurtz, was that the sighting was likely caused by a blimp, noting that there were known blimp operations in the Washington area at the time. Handwritten annotations on the report highlight contradictions in the witness statements and suggest that the sighting was likely a blimp, despite some confusion regarding the location of the observers.
