Project 10073 Record Card and Incoming Message regarding 10 April 1964 Sighting

This document consists of a Project 10073 Record Card and an associated Department of the Air Force incoming message regarding a series of sightings reported by Captain D. Dunlap of the USMC, piloting a KC-130F aircraft on April 10, 1964. The pilot reported three separate observations while flying at 25,000 feet over the Atlantic Ocean. The first sighting involved an object observed through a sextant at 50 degrees elevation; it appeared round with a tail, was the same color as stars, and was distinguished from stars by its relative motion. The second sighting involved seven surface vessels arranged in a curving train, which displayed no apparent movement or distinct outlines, only lights. The third sighting involved two unidentified aircraft flying in a loose formation with steady red lights. These aircraft were observed at the pilot's two o'clock position and later at the eleven o'clock position. The pilot estimated their speed at approximately 500 knots. Radar contact was maintained on these aircraft for five minutes after they were no longer visually observed. The official conclusion on the record card suggests the possibility of a balloon observation with a package, noting the lack of radar pickup for the first sighting, while the third sighting remains categorized as having insufficient data for evaluation.
