Project 10073 Record Card — Sighting of 5 August 1957

This document contains a Project 10073 record card and associated technical information sheets regarding a UFO sighting reported on 5 August 1957 in Silver Springs, Maryland. The witness, a 30-year-old male who identified himself as a military intelligence research specialist, reported observing seven blue-white luminous objects in a 'V' formation at approximately 8:25 PM. The witness described the objects as having no sound, being the size of a 'head of a pin' at arm's length, and moving in a steady path toward the North. He estimated the objects were at an altitude of 100,000 feet and traveling at 1200 mph. The witness also claimed that a circular transparent field surrounded the formation and that the light from the sky was refracted in a circular manner. The witness stated he viewed the formation through binoculars and that his eyes were checked at 20/10 in 1954. The report includes detailed notes from Air Force evaluators, including personnel from the Bio-Physics lab, who expressed significant skepticism regarding the witness's reliability. Evaluators pointed out that it would be impossible to estimate an altitude of 100,000 feet at night, especially if the objects appeared as small as a pinhead. They further noted that even a B-36 aircraft would be difficult to see at that altitude, and that the witness's reported speed and duration were mathematically contradictory. The file includes handwritten calculations attempting to verify the witness's claims, which ultimately led to the conclusion that the source was unreliable and the report contained contradictory information. The document also includes a copy of a U.S. Ground Observer Corps (GOC) guide illustrating the appearance of a B-36 at various distances, used to demonstrate the implausibility of the witness's observations.
