Project Blue Book Case File
Dayton, OhioJune 1963
Summary
On the evening of June 8, 1963, a woman in Dayton, Ohio, reported seeing an object in the night sky that resembled a bright star. The object appeared to fade in and out, with brightness comparable to the largest stars visible. She noticed that the object seemed too high in the sky to be an aircraft, and it moved at a uniform speed in a northeast direction. Because of these characteristics, it reminded her of the Soviet satellite Sputnik.
The U.S. Air Force investigation that followed focused on a specific possibility. Satellite ECHO, a large communications satellite used for relaying radio signals, passed over Dayton on the evening of the sighting. The satellite's position at the time (21:47 local time, south of the city at 38 degrees above the horizon, heading northeast) roughly matched the witness's description. The Air Force concluded that the woman had observed the ECHO satellite, not an unidentified flying object.
