Project 10073 Record Card — Osgood, Indiana, 13 March 1961

This document contains a Project 10073 record card and associated correspondence regarding a UFO sighting reported by a civilian in Osgood, Indiana. On March 13, 1961, between 1955 and 2000 hours EST, the witness observed a light resembling a star moving from the low South toward the Southeast, reaching an elevation of approximately 40 to 45 degrees. The witness noted that the object oscillated in brightness, changing from bright to dim and back to bright. The witness, who had previously observed the Echo satellite the previous summer, questioned whether this object was also the Echo satellite. Following the report, the Air Technical Intelligence Center (ATIC) coordinated with the National Space Surveillance Center. The investigation concluded that the object observed by the witness was indeed the U.S. satellite Echo I. The correspondence, signed by Colonel Philip G. Evans, confirms that the witness was to be advised of this finding. The documentation includes the original record card, a formal memorandum from the Deputy for Science and Components, and the handwritten letter from the witness requesting an explanation for the sighting.
