Project 10073 Record Card: Sighting near Denver, Colorado, 5 August 1956

This document is a Project 10073 record card and associated teletype report detailing a UFO sighting that occurred on August 5, 1956, near Denver, Colorado. The report describes an observation made by three individuals—a 1st Lieutenant from the 3416th Student Training Squadron at Lowry AFB, an electrician, and a radio technician. The witnesses reported seeing six round, pale orange objects, each approximately the size of a pea, flying in a triangular formation. The sighting lasted for ten seconds. The objects were observed moving in a straight line that gradually curved toward the east. The witnesses observed the objects using both the naked eye and a telescope. The report includes a hand-drawn diagram illustrating the observer's position and the trajectory of the objects. Weather conditions at the time were described as clear and unlimited. Official records indicate that no radar contact was made in the area during the time of the sighting, as confirmed by the Air Route Traffic Control (ARTC). The final conclusion reached by the investigating authorities was that the observation of meteors was the most probable cause for the phenomenon. The documentation includes the original record card, the teletype transmission from the Commander of the Air Defense Command at Ent AFB to the Director of Intelligence at USAF Headquarters, and supplemental data regarding the observers and atmospheric conditions.
