Project 10073 Record Card and Air Intelligence Information Report — 19 August 1952

This document is an Air Intelligence Information Report regarding a sighting of unidentified flying objects near Lancaster, Pennsylvania, on 19 August 1952. The report, authored by 2d Lt. John L. Spiegel of the Middletown Air Materiel Area, details an observation made by two members of the Ground Observer Corps. The primary witness described an object resembling a yellow toy top or a naval buoy, which exhibited swaying, up-and-down motion. The object was observed at an estimated altitude of 500 feet and appeared to move slowly, though it was noted to move quickly on occasion. A second, orange-colored object was also observed moving down over the horizon during the same period. The observation lasted between one and two minutes under clear weather conditions with calm winds. Although the sound of an aircraft was heard, it could not be definitively linked to the objects. The report concludes that there is no definite explanation for the sighting, suggesting the possibility of an exceptionally bright star or a weather balloon. The document includes a Project 10073 record card and a weather data sheet, though the latter contains no data. The report was distributed to the Air Technical Intelligence Center (ATIC) and Headquarters USAF.
