This Project 10073 record card documents a sighting that occurred on July 16, 1956, in Oklahoma City, Oklahoma. The report was initiated following a letter received from the Commander of the Ground Observer Squadron of Oklahoma City. The observation involved three objects, each appearing to consist of two lights, which were described as being the size of a silver dollar when held at arm's length. The objects were observed heading west at an estimated altitude of 5,000 feet. Witnesses reported hearing a sound described as a rhythmic beat, similar to a rumble, with one observer characterizing it as a pulse. The duration of the sighting was recorded as two to three minutes. The official conclusion reached by the evaluating authority was that the sighting was not anomalous.
