Project 10073 Record Card — Hollis, Long Island, N.Y., 19 September 1957

This document is a Project 10073 record card detailing a UFO sighting that occurred on 19 September 1957 in Hollis, Long Island, New York. The report describes a single, round object, approximately the size of a basketball held at arm's length, which appeared shiny, silver, or grey. The witness, identified as a former WWII gunner, reported that the object was initially slow but then moved in a northwesterly direction at an unusual speed. The observation lasted for approximately three minutes. The report includes a detailed breakdown of the sighting, noting that the witness observed a DC-6 aircraft in the vicinity at a low altitude. The official conclusion reached by the Air Technical Intelligence Center (ATIC) and the Air Division intelligence officer was that the object was a weather balloon, with the perceived unusual speed explained by wind conditions at various altitudes. The documentation includes a series of teletype messages and internal record cards confirming the evaluation and the concurrence of military intelligence personnel regarding the balloon explanation.
