Project 10073 Record Card: Sighting at Lake Silkworth, Pennsylvania, 2 May 1957

This document consists of a Project 10073 record card and an associated military teletype message regarding a UFO sighting that occurred on May 2, 1957, at Lake Silkworth, Pennsylvania. A civilian witness reported observing a single, round, grey, pea-shaped object directly overhead for a duration of 15 minutes. The object was described as stationary before eventually moving out of range at a 45-degree angle to the east. The report notes that the observation was made via ground visual means and that no radar contact was established. The military report, originating from the 648th AC&W Squadron at Benton AFS, was transmitted to various commands, including the Air Technical Intelligence Center at Wright-Patterson AFB. The official conclusion reached by the military authorities was that the sighting was caused by a weather balloon. This determination was supported by the Assistant Operations Officer for Weather, Lieutenant Eugene I. Halbachn, who provided meteorological data for the time and place of the sighting, noting clear conditions with winds at 10,000 feet.
