In 1947, a strange object fell from the sky near Roswell, New Mexico, and controversy brewed over what it really was. In November 2001, we convened a team of experts at the National Archives for an exclusive first look at the top-secret government files of the UFO incident. We unveil the remaining classified files--11 boxes with 17 notebooks of declassified files, photos, transcripts and audiotapes of dozens of witnesses, and 22 films and videos--in a definitive statement on the 50-year-old mystery.
