The Kecksburg UFO incident took place on 9 December 1965, when a bright fireball crossed the sky over the Great Lakes region and something was reported to have fallen into woods near Kecksburg, Pennsylvania, about 50 km southeast of Pittsburgh. Residents later described an acorn-shaped object removed by the military, but official searches reported finding nothing, and astronomers concluded the fireball was a meteor.[1][2]
The fireball
At about 4:44 p.m. Eastern time, a fireball was seen over the Detroit–Windsor area and in several U.S. states and Canada. Reports followed of hot metal fragments in Michigan and northern Ohio, small grass fires, and sonic booms in the Pittsburgh area. The Federal Aviation Administration logged 23 reports from pilots, and a seismograph south-west of Detroit recorded shock waves.[1]
Kecksburg
In Kecksburg, residents reported blue smoke, a vibration and a thump, and something falling into the woods. State police and Army personnel roped off the area, and the search found "absolutely nothing", according to official statements; a local headline read "Searchers Fail to Find Object". In later decades some residents and the local radio reporter, John Murphy of WHJB, described an object about the size of a Volkswagen Beetle, shaped like an acorn, with markings resembling hieroglyphics around its base, which they said was taken away on a military flatbed truck.[1][3]
Explanations

Early statements from astronomers and a Defense Department spokesman favoured a natural meteor or bolide. A 1967 analysis in the Journal of the Royal Astronomical Society of Canada by Chamberlain and Krause, using photographs and witness reports, concluded that the fireball followed a steep path from south-west to north-east and probably came down near Windsor, Ontario, far from Kecksburg.[1][4]
Spaceflight writer James Oberg proposed in 1991 that the object might be the Soviet Venus probe Kosmos 96, but later NASA comments said the fireball's path was too steep for a re-entry and that tracking showed Kosmos 96 had come down hours earlier. Other researchers speculated about a U.S. re-entry vehicle; none of these ideas has been confirmed.[1][5]
The NASA lawsuit
In 2005 NASA said experts had examined metallic fragments thought to be from a Soviet satellite but that the records had been lost. Journalist Leslie Kean sued NASA under the Freedom of Information Act, and on 26 October 2007, under a court order, NASA agreed to search for the files; its liaison officer testified that two boxes of documents were missing. Oberg argued NASA probably never held relevant documents.[1][6]
Legacy

A 1990 episode of Unsolved Mysteries made the case famous, and a prop "acorn" from the program is displayed in the village. The 2003 Sci Fi Channel documentary The New Roswell: Kecksburg Exposed added further claims. The incident inspired the films Kecksburg (2019) and partly The Vast of Night (2019).[1][3]
