Project 10073 Record Card — Sighting Report, Cleveland, Ohio, 30 July 1957

This document is a Project 10073 record card and associated military communications regarding an unidentified aerial phenomenon sighting on July 30, 1957. The primary witnesses were the pilot and co-pilot of Capital Airlines Flight 841. According to the report, the crew observed a large, round, yellowish-white object that appeared brilliant, then dimmed, and returned to a brilliant state. The object was reported to have no sound and was described as moving at an extremely fast speed. The sighting occurred near Cleveland, Ohio, at an altitude of 20,000 feet (referred to as '20 angels'). The object initially hovered over Cleveland before moving in a northwesterly direction. The aircraft attempted to chase the object, but it sped ahead of them and disappeared over the horizon. The weather conditions were reported as clear. Both pilots explicitly stated their belief that the object was neither a star nor a jet. The report was processed by the 662nd ACWRON and forwarded to various military commands, including the Air Defense Command and the Air Intelligence Service Squadron. The final conclusion recorded on the project card is 'UNIDENTIFIED'. The document includes the original record card, a teletype transmission, and a summary report detailing the incident.
