Unusual UFO Report - Pepperrell Air Force Base

This document is a briefing note dated July 12, 1955, addressed to the Acting Assistant Director for Scientific Intelligence from the Chief of the Physics & Electronics Division. It serves as a preliminary report regarding an unusual unidentified flying object sighting reported from Pepperrell Air Force Base in Newfoundland. The report details a dual-observation event involving a KC-97 tanker aircraft pilot and a ground radar site. The sighting is noted as being particularly unique because the pilot of the aircraft, identified as 'Archie 29', maintained visual contact with the object while simultaneously coordinating direction changes with the ground radar controller. The document notes that these direction changes correlated exactly between the visual and electronic observations. The event lasted for at least 49 minutes, which the author contrasts with previous cases that typically lasted only a few minutes. The document concludes by stating that further information is expected upon the issuance of the complete report, identified as AF Form 112.
