Project 10073 Record Card — Dunedin, Florida, November 1957

This document is a collection of reports and records concerning Unidentified Aerial Phenomena (UAP) sightings occurring in early November 1957. The primary record is a Project 10073 card documenting a sighting in Dunedin, Florida, on November 4, 1957. A civilian witness reported observing a round, silver object, approximately the size of a basketball at arm's length, with a tail four times its length. The object moved slowly south for seven to eight minutes. The official conclusion recorded on the card is that the sighting was caused by a jet aircraft leaving non-persistent contrails. The document also includes teletype communications and press clippings regarding separate, concurrent sightings at the White Sands Proving Grounds in New Mexico. These reports describe two military police patrols observing a 'very bright' object near the Trinity Site, the location of the first atomic bomb explosion. Descriptions of these objects varied, with some reports mentioning a cigar-shaped object 200 feet long, while others described an egg-shaped object. Military personnel at White Sands reported the object hovered or touched down briefly. Dr. Lincoln La Paz, a meteoriticist at the University of New Mexico, is quoted in the press clippings as stating that the objects were likely man-made or attributable to meteoritic phenomena, dismissing theories of extraterrestrial origin. The document highlights a discrepancy between official Air Force explanations—which suggested the planet Venus or cloud formations—and the reports provided by the military patrols on the ground. The file includes technical details such as radar unit responses, weather conditions, and the specific observations of the witnesses involved in the various incidents.
