Project 10073 Record Card and Related Correspondence — Regina, Canada / Opheim, Montana, May 1960

This document collection details a UAP sighting incident occurring on May 7, 1960, involving reports from Regina, Canada, and radar stations in Opheim, Montana, and Fortuna, North Dakota. The initial report described two white points of light that traveled north, proceeded east, and stopped, remaining visible for approximately one hour. A separate witness report, attributed to a former naval air gunner, described a large orange spherical object hovering over Route 20. Military authorities, specifically the 29th Air Division (SAGE), conducted an investigation involving radar data from the 779th and 780th Aircraft Control and Warning (ACW) squadrons. The official conclusion reached by the Air Technical Intelligence Center (ATIC) was that the object was a Pibal weather balloon released from a Canadian airport. The movement of the balloon was found to correlate with the observed UFO. Furthermore, investigators, including Major John Rudovsky, suggested that the presence of strong Northern Lights during the incident caused radar jamming by reflecting off the balloon, which explained the electronic anomalies reported by the radar stations. An F-101B interceptor was scrambled to investigate the object but failed to make an interception or visual contact. The documentation includes the original Project 10073 record card, military teletype messages between command units, and a technical information sheet.
