Just before five in the afternoon on December 9, 1965, a brilliant fireball crossed Michigan, Ohio, Pennsylvania and neighboring states. Near the village of Kecksburg, some residents said they saw something fall into the woods.
Bill Bulebush, who said he was first to reach it, described a smoldering, sparking object about ten feet long, shaped like an acorn, with markings like hieroglyphics around its base. Volunteer firefighter James Romansky described a bronze acorn about the size of a Volkswagen Beetle. Residents said state police and soldiers closed the area, and one man who was ten at the time said he saw a flatbed truck leave with something that size on it. Officials said nothing was found.
In 2003 journalist Leslie Kean sued NASA for its records. In 2007, after a court ordered a search, a NASA official testified that two boxes of records from that period were missing. Much of the detail about the acorn comes from interviews given decades later, beginning with Unsolved Mysteries in 1990.
