Project 10073 Record Cards and UFOB Reports — Kansas City, Missouri, September 1957

This document contains two Project 10073 record cards and associated teletype reports regarding unidentified aerial phenomena observed in the vicinity of Kansas City, Missouri, in September 1957. The first incident, occurring on 17 September 1957, involved a civilian witness who observed a round, white object moving rapidly across the sky in an ENE direction for three to five minutes. The witness, an arc welder, reported that the object moved faster than an aircraft and made no sound. The official conclusion for this event was that the object was likely an aircraft, based on the observed maneuvers and duration. The second incident, reported on 26 September 1957, involved a sighting of two white objects with a trail, observed for 10-15 seconds. The report notes that the second light could have been a tail or trail. The official conclusion for this second event was that it was likely an aircraft, but the report explicitly states that a definitive conclusion could not be reached due to insufficient data, with a possible meteor also being considered as an explanation. The documents include standard military reporting formats, including teletype headers from the 20th Air Division and the Lowry Flight Service Center, and provide details on weather conditions, witness information, and flight paths. The reports were processed under the guidelines of CONADM 55-1.
