Project 10073 Record: Incident #364

This document contains the official record and associated teletype communications regarding an Unidentified Aerial Phenomena (UAP) sighting reported on June 10, 1949. The incident, designated as Incident No. 364 under Project 10073, involved a pilot from the 58th Fighter Squadron stationed at Otis Air Force Base, Massachusetts. While flying an AT-6 aircraft at an altitude of 4,000 feet, the pilot observed a white, tubular object approximately 100 feet in length. The object was sighted at an estimated altitude of 30,000 feet, positioned 20 miles southwest of Boston, Massachusetts. The pilot reported that the object was traveling at a speed of approximately 100 to 150 mph on a heading of 330 to 340 degrees. The object appeared to be oriented perpendicular to the earth and exhibited no visible exhaust, trail, or sound. The pilot attempted to chase the object but lost visual contact when it entered an overcast cloud layer. The report notes that there were no photographs taken and no physical evidence recovered. The official conclusion reached by the evaluating authorities was that there was insufficient data to identify the object. The documentation includes multiple teletype messages sent between military units, including the Olmsted Flight Service Center and the Air Materiel Command at Wright-Patterson Air Force Base, confirming the details of the report and the pilot's unsuccessful interception attempt.
