Project 10073 Record Card — Las Vegas, Nevada, 30 May 1960

This document consists of a Project 10073 record card and an associated teletype report regarding an Unidentified Aerial Phenomena (UAP) sighting that occurred on May 30, 1960, in Las Vegas, Nevada. The incident was reported at 2145Z by two individuals, one of whom was identified as a director of research and development for an airline, and the other as an employee of an advertising agency. The primary witness, noted for having good reliability and aviation experience, reported observing a white and dark object that appeared to be the size of a 'head of a pin.' The object was traveling on a northwest course at extreme speed and height, approximately 75-80 degrees above the horizon. The witness observed the object disappear behind clouds and subsequently reappear as two distinct objects. The object also performed a hard 90-degree turn. The total duration of the sighting was estimated at one to two minutes. The report notes that weather conditions were characterized by high scatter with unlimited visibility and moderate winds. The sighting was processed by the Nellis AFB Intelligence Section and forwarded to the Air Technical Intelligence Center. The official conclusion reached by the investigators was that the case provided insufficient data for a definitive identification. The report explicitly states that if the observer had not been a person well-qualified in aviation, the object would have likely been classified as a probable aircraft; however, given the observer's professional background and familiarity with aviation, the case was categorized as having insufficient data.
