Project 10073 Record Card — Oklahoma City, Oklahoma, 28 September 1956

This document consists of a Project 10073 record card and associated teletype reports regarding an Unidentified Flying Object sighting over Oklahoma City, Oklahoma, on September 28, 1956. The sighting, which lasted over 50 minutes, involved a single round, oval-shaped object described as white or luminous yellow, and in one report, as bright metallic. The witness, a traffic clerk for Braniff at Will Rogers Field, observed the object moving in an ascending course to the west, leaving a tail to the southwest. The object was reported to have no sound. The military investigation involved 1st Lt. Homer R. Hargrove, who consulted with Captain Mills. Captain Mills identified the object as a weather balloon, citing information provided by two individuals, Mr. Leber and Mr. Crawford. The official record card reflects this conclusion, noting that while the reporting officer was certain it was a weather balloon, the evaluation process found the evidence insufficient to fully confirm the identification, ultimately classifying the event as 'probably balloon'. The documentation includes multiple teletype transmissions (OPS 9-50 and OPS 9-51) detailing the description, weather conditions, and the administrative handling of the report by the 745th ACWRON and the Air Technical Intelligence Center.
