A couple in Albuquerque, New Mexico, reported observing an unidentified aerial phenomenon on August 25, 1951. The object, described as chevron-shaped and estimated to be one and a half to twice the size of a B-36 bomber, was seen flying over the city. Witnesses noted that the object made no noise, had white lights on its wings, and traveled at an estimated speed of 300 to 400 mph. Despite multiple investigations, no conventional explanation for the phenomenon was found.
