It's an age-old question: Are we alone in the universe? Now, 60 years after the reported crash of a UFO in Roswell, N.M., and with the French government releasing its UFO archives, there are new efforts to prove alien spacecrafts really exist. James Fox, the producer of [the documentary] Out of the Blue, says that aliens are out there. He also believes that they have incredible technical ability, saying that they can "fly rings around our fastest jets." Out of the Blue is an attempt to weed out the wackos and present credible witnesses who say they saw what looked like alien spacecraft. Witnesses like former President Carter, who said, "I saw one, but I don't know where. It just disappeared." And Mercury astronaut Gordon Cooper, who says he saw "this typical saucer shape, double-cylindrical shape, metallic." The subject of UFOs is one of those things that never gets a satisfactory answer, and never quite seems to go away. The documentary begins with an ... incident that occurred in Phoenix in March 1997, known as the "Phoenix Lights." Hundreds and possibly thousands of people, many of them looking at the Hale-Bopp comet, reported seeing an array of lights and an enormous delta-shaped craft. The first report of a strange flying object came about 8:20 p.m. from a former police officer in Paulden, Ariz. Over the next 40 minutes, people gave similar reports of an object along a 20-mile route south to Phoenix and Tempe. Among other claims, Fox focuses on a 1980 report of UFO sightings at an American air force base in England - the so-called "Bentwaters" incident. Three former Air Force security officers told Fox about actually touching a small, strange craft that landed outside the base.
