Indeed, 1947 was a watershed year for the UFO phenomenon. What Kenneth Arnold started in June of 1947 was eclipsed by events that unfolded during the first month of July. A UFO reportedly crashed near a ranch in Roswell, New Mexico. At first the U.S. Army Air Force confirmed that a UFO had crashed and newspapers quickly spread the amazing news. The military then changed their story, claiming that is was actually debris from a weather balloon that fell that day in Roswell. Roswell is considered by most to be the single most well-known UFO incident in history.
