PROJECT 10073 RECORD - Sighting Report 30 May 54

This document is a Project 10073 record detailing an unidentified aerial phenomenon sighting that occurred on May 30, 1954, at 2340Z near Las Vegas, Nevada. The report was generated by the Commander of the March Flight Service Center at March Air Force Base, California, and distributed to various Air Force commands, including the Air Technical Intelligence Center (ATIC) at Wright-Patterson Air Force Base. The sighting was reported by two Air Force pilots, Major J. L. Giannini and 1st Lt. W. J. Ryan, who were flying a C-47 aircraft (AF43-49273) at an altitude of 10,000 feet. The pilots observed a single, cylindrical object, described as being approximately the size of a B-36 bomber, lacking wings or tail surfaces, and gray in color. The object was observed for approximately 10 seconds, traveling at what the pilots described as a 'phenomenal' speed at an altitude estimated between 8,000 and 10,000 feet. The object was moving on a heading of 065 degrees. The weather conditions at the time were reported as clear with 30 miles of visibility. The official conclusion recorded in the document states that while a meteor was considered a possibility based on the flight characteristics and duration, the available data was insufficient for a firm evaluation. The report includes standard administrative details, such as the aircraft type, pilot names, and the specific coordinates or location markers associated with the sighting.
