Project 10073 Record Card — Chandler AFS, Minnesota, 8 December 1956

This document comprises a Project 10073 record card and an accompanying military teletype report regarding an unidentified aerial phenomenon observed on December 8, 1956, at Chandler Air Force Station, Minnesota. The report, filed by the Commander of the 787th ACWRON, details a sighting by an Airman First Class (Radar Maintenance) at approximately 0130Z. The witness described a single, round object, white in color, which turned green as it descended. The object was estimated to be the size of a baseball at arm's length and was observed for a duration of 20 to 30 seconds. According to the report, the object moved toward the earth at an angle of approximately 20 degrees, then leveled off and initiated a slight climb before disappearing. The witness noted that the object appeared similar to a falling star but expressed surprise at the observed changes in altitude and speed. The official conclusion reached by the Air Technical Intelligence Center (ATIC) was that the sighting was caused by a meteor, and the reported 'slight rising' of the object was dismissed as an optical illusion. The document includes meteorological data for the area, noting clear skies with 15 miles of visibility. The report was submitted in accordance with Air Force Regulation 200-2, dated August 12, 1954.
