Part of the In Search Of series, this documentary explores the strange world of unidentified flying objects, commonly known as UFOs. Narrated by series host Leonard Nimoy, this video attempts to prove the existence of the UFO with interviews with scientists who support or refute the theory of aliens from other planets or galaxies. Air Force investigators talk about their research into this controversial topic and report on the validity of supposed alien and UFO Earth landings, including the most notorious one in Roswell, NM. There are also interviews with people who have claimed they sighted UFOs, both flying or on the ground. ~ Cecilia Cygnar, Rovi
