Project 10073 Record Card and Related Correspondence — New York, August 1959

This document details the investigation of a UFO sighting reported on August 25, 1959, in New York. A civilian witness observed a single white, sparkling object, described as being the size of a half-dollar, moving vertically with a double exhaust and immediate spurts. The object was observed for 5 to 10 minutes before disappearing into the clouds. The initial report was processed by the 2500th Air Base Wing and forwarded to the Air Technical Intelligence Center (ATIC) under Project 10073. ATIC requested further information regarding the witness's friend, who had been present but was unable to obtain binoculars before the object vanished. Subsequent correspondence reveals that the witness moved and could not be located for further questioning. The investigation concluded that the object was a weather balloon released from the New York International Airport one hour prior to the sighting. A temperature inversion between 5000 and 6000 feet was noted by Captain Hall as a potential factor in the observation.
