PROJECT 10073 RECORD CARD — 5 Mar 58

This document is a Project 10073 record card and associated military cable detailing a UFO sighting that occurred on March 5, 1958. The witness, a Major Knapp, was piloting a T-33 aircraft at an altitude of 33,000 feet when he observed a bright green, round object. The sighting took place 66 nautical miles northeast of Louisville, Kentucky, at approximately 0057Z. The object was observed for a duration of two to six seconds. According to the report, the object appeared in the field of vision ten degrees above the horizon, moved to five to ten degrees below the horizon, and then either burned out or entered an overcast layer. The witness noted that the object did not appear to be falling as fast as a typical star. The report includes weather conditions at the time, noting a 55,000-foot overcast layer and surface winds from the ESE at 7 knots. The military investigation, conducted by the Air Technical Intelligence Center (ATIC), concluded that the evidence was limited but strongly suggested the object was a meteor. The documentation includes a formal record card and a teletype message sent from the 85th Air Division to various commands, including the Assistant Chief of Staff for Intelligence at HQ USAF and the Air Defense Command at Ent AFB. The final assessment recorded on the document is 'Astronomical - Meteor'.
