Project 10073 Record Card and Incident Report — Waterloo, Iowa, June 1957

This document consists of a Project 10073 record card and a supporting military teletype report regarding an unidentified aerial phenomenon observed on June 2, 1957, in Waterloo, Iowa. The sighting occurred at 2015 local time (0215Z). The witness, identified as a member of the Highway Patrol, reported observing a single object described as being the size of a pea and colored pink. The object was initially observed at a 290-degree azimuth and 10-degree elevation. It remained stationary before moving down toward the horizon. The report notes that there were no maneuvers and no radar contact was made. The weather conditions at the time were reported as clear. The official conclusion reached by the investigating authorities was that the object was the moon. The report explicitly states that the moon's position and the fact that it was setting, combined with the proximity to the sun which had already set, were contributing factors to the misidentification. The teletype, sent by the 788th ACWRON at Waverly AFS, Iowa, was addressed to various military commands, including the Air Technical Intelligence Center at Wright-Patterson Air Force Base and the Director of Intelligence at HQ USAF in Washington, D.C. The document is marked as unclassified and references Air Force Regulation 200-2 regarding Unidentified Flying Objects (UNFOB).
