Unidentified Flying Objects Sighted Near Las Vegas, Nevada 15 July 1952

This document is a collection of reports and teletype communications regarding a sighting of two unidentified flying objects over Las Vegas, Nevada, on July 15, 1952. The primary report, IR-505-52, issued by the Flight Service of the Military Air Transport Service (MATS), details the accounts of several civilian witnesses, including a former weather observer and radio technician. The witnesses described two lens or cigar-shaped objects, white or silver in color, moving in a smooth, rapid glide toward the west. The objects were reported to have no jet stream or vapor trails and were estimated to be moving faster than jet aircraft. The duration of the sighting was estimated at approximately 30 seconds to one minute.

Official investigations included inquiries with the Las Vegas Interstate Airways Communications Station (INSAC), which reported no air traffic under their control in the vicinity at the time of the sighting. However, the report notes that Nellis Air Force Base had several flights of jet aircraft on local training missions in the area. The investigating officer, Major Gerald E. Tyler, noted that while Las Vegas residents are generally familiar with jet aircraft, it was impossible to definitively correlate the sighting with specific training flights because the aircraft did not file flight plans and could have been anywhere in the local flying area. The report concludes that no physical evidence was obtained and no interception or identification was reported. The document includes witness statements, sketches of the objects, and teletype messages (DMZ 8161) confirming the details of the sighting. The overall assessment remains inconclusive, highlighting the difficulty in distinguishing between unidentified phenomena and local military training activities.
