Project 10073 Record Card — Harrisburg, PA, 5 March 1958

This document is a Project 10073 record card detailing an unidentified aerial phenomenon sighting reported on March 5, 1958, in Harrisburg, Pennsylvania. The witness, a 13-year-old civilian, reported observing a single, long, red, and orange cigar-shaped object at approximately 0130Z. The observation lasted for one minute, during which the object was seen traveling in a northeast direction before disappearing into a cloud bank. The report includes a teletype communication from the Commander of the 2855th Air Base Wing at Olmsted Air Force Base to the Air Defense Command at Ent Air Force Base and the Air Technical Intelligence Center (ATIC). The official evaluation provided by the military authorities concluded that the object was likely a jet aircraft with its afterburners engaged at a high altitude. The document also contains handwritten annotations and queries regarding the witness's description, such as questioning how the 'round' shape was determined and requesting clarification on the object's size. The report notes the presence of cloud cover at the time of the sighting and confirms that no radar contact was made. The final assessment remains that the sighting was likely a conventional aircraft.
