Triangular UFO seen over El Centro in 1958

Summary

A couple in El Centro, California, observed a black triangular object with blinking lights in 1958. The object, the size of a silver dollar at arm's length, appeared at 45 degrees above the horizon and moved north for one minute. Although no photos were taken and there was no sound, the witnesses described blue-gray lights on the underside that flickered. The official report classified it as an aircraft, but the detailed description suggests something unusual.

The official report considered it an aircraft, but the lack of noise, exhaust, or clear identification raised doubts. The observer, a USAF employee, had experience with aerial observations, adding credibility to his testimony. Despite ideal weather conditions, no clear explanation was found for the phenomenon, leaving open the possibility that it was an unidentified object.
