This document is an Air Intelligence Information Report (IR-1-57) dated 4 December 1957, detailing a sighting of an Unidentified Flying Object that occurred on 26 November 1957 at 2205 hours. The witness, an electronics technician employed by Edgerton, Germeshausen & Grier Inc., reported observing a round, yellow-orange object approximately the size of a half dollar. The object was in sight for 5 to 7 seconds, moving on a straight, slightly downward trajectory before disappearing behind a mountain range. The witness, who was located in Brentwood Park, Las Vegas, Nevada, estimated the object's altitude at 25,000 feet. The report includes a detailed weather analysis from the Air Weather Service at Nellis Air Force Base, which confirmed clear conditions at the time of the sighting. The investigating officer, 1st Lt. Charles Elliott, interviewed the witness and noted that the individual appeared to be well-educated and familiar with such phenomena. The official conclusion reached by the intelligence personnel was that the description, duration, and flight path of the object indicated a high probability that it was a meteor. Handwritten notes on the report further support this conclusion, citing that the angle and flight path were typical of true meteors and noting that the area is a known source of reports regarding bolides or fireballs. The report includes an enclosure featuring a map of the area with the line of sight marked.
