Project 10073 Record Card — M.V. Box Hill Sighting, 11 June 1963

This document contains a Project 10073 record card and associated correspondence regarding a sighting reported by the crew of the M.V. Box Hill, a British vessel employed by the United Fruit Company. On 11 June 1963, at 0650Z, while in the Gulf of Mexico at position 25.8N 89.56W, the crew observed an object of magnitude 2.0. The object was seen rising between the stars Merah and Piecda in the constellation Ursa Major. It was tracked on a bearing of 320 degrees True, disappeared behind clouds at 008 degrees True, and reappeared at 0705Z on a bearing of 053 degrees True at an altitude of 10 degrees before being lost to view at 0710Z. The weather was described as clear with bright moonlight, a 10 mph easterly wind, and a temperature of 28 degrees Celsius. The report was forwarded through the U.S. Naval Oceanographic Office to NASA and subsequently to the U.S. Air Force Technical Intelligence Center at Wright-Patterson AFB. The official conclusion reached by the investigators was that the object was a satellite and not a UFO, specifically noting it was not the ECHO I satellite.
