This document consists of a Project 10073 record card and an associated teletype report regarding an unidentified aerial phenomenon observed on September 7, 1954, near Las Vegas, Nevada. The report was prepared by Captain Richard J. Littleton of the 3595th Flying Group at Nellis Air Force Base. The primary witness, an electronics supervisor with the ETOQ Maintenance Squadron, reported observing a single object at 1235Z. The witness described the object as having a conical shape with a rounded nose that tapered to a point at the tail. Initially black, the object changed to a bright orange color and exhibited an orange flame at the rear. The witness noted that there were no features or trails associated with the object, but reported feeling a vibration in the air during the sighting. The object was observed moving in a straight line from an elevation of 60 degrees to 65 degrees at a 270-degree azimuth. The total duration of the sighting was less than one minute. At the time of the incident, the area was experiencing thunderstorms with black storm clouds. The official conclusion recorded on the card is that the object was a possible meteor.
