Project 10073 Record — Bucks Harbor AFS, Maine, December 10, 1967

This document contains records and correspondence regarding a UFO sighting reported on December 10, 1967, near Bucks Harbor AFS, Maine. The primary witness, A1C Salvatore A. Difilippo, reported observing a single, red-yellow, teardrop-shaped object that was slightly larger than a grapefruit. The object was observed for 1 to 3 minutes, moving in a direct, straight-like path from left to right before moving rapidly up and away. The witness described the object as having a yellow glow and blurring speed, with no audible sound. The initial report was filed under Project 10073 but was marked as having 'insufficient data for evaluation' because the local investigation did not follow standard Air Force regulations (AFR 80-17). Consequently, Lt. Col. Hector Quintanilla, Jr., Chief of the Aerial Phenomena Office, directed the 907th Radar Squadron to resubmit the report and include all agencies contacted during the investigation. Further analysis of the incident, including meteorological data from the 'STAR TREK' project, led the Air Force to conclude that the object was likely a weather balloon released at 0018 hours, shortly before the 0026 sighting. The report notes that radar typically does not detect such balloons unless they are equipped with a metal reflector. The documentation includes a map of the Louisville area, which appears to be an attachment or reference material related to the broader administrative handling of such reports.
