Project 10073 Record Cards and Associated Messages — October 1956

This document contains a collection of Project 10073 record cards and associated teletype messages documenting two separate UFO sightings in Pueblo, Colorado, during October 1956. The first incident occurred on 1 October 1956, involving a single cream-colored, star-like object observed for approximately one and a half seconds. The witness described the object as having the size of a pea at arm's length and noted it left no trail and made no sound. The official evaluation concluded that the sighting was a meteor. The second incident occurred on 26 October 1956 and involved a group of 20 to 30 bluish-green, round objects. Witnesses reported that the objects initially appeared in a spread V-formation before tightening into a V-formation, moving from the northeast to the southwest at a speed described as faster than a jet. These objects were observed for approximately ten seconds before disappearing into hazy clouds. The official conclusion for this second event was that the objects were likely a flight of high-flying migratory birds. The documentation includes the original record cards, which summarize the observations, and the subsequent military teletype messages sent between the 462nd AISS at Ent Air Force Base and the Air Technical Intelligence Center at Wright-Patterson Air Force Base. These reports were processed as part of the Air Force's ongoing investigation into unidentified aerial phenomena under Project 10073.
