Project 10073 Record Card — Miamisburg, Ohio, 27 November 1957

This document contains a Project 10073 record card regarding a UFO sighting reported near Miamisburg, Ohio, on 27 November 1957. A civilian witness observed a very faint object traveling from the NNW to the SSE for approximately three minutes, beginning at 1811 EST. The report includes a hand-drawn diagram illustrating the observer's perspective and the object's path relative to the horizon. The official conclusion reached by the Air Technical Intelligence Center (ATIC) was that the object was likely the Soviet satellite Sputnik I, as the reported time and trajectory closely matched the satellite's known orbital track. The file also includes a letter of information from Major Harry Griffin, Base Provost Marshal, dated 9 December 1957, which references correspondence with the witness and confirms that no further action was required. Additionally, a press clipping from a local newspaper is included, featuring comments from F. E. Sutter and Kenneth E. Kissell of the Miami Valley Astronomical Society, who also identified the object as the rocket of Sputnik I. A list of other UFO sightings found to be Soviet satellites is also provided, documenting similar reports from locations including Elmendorf, Alaska, and Globe, Arizona.
