Part 1: BIG WOODS, BRIGHT LIGHTS: DECEMBER 11, 1996: Two cousins, Billy and John Smith, are driving in separate cars along the Klondike Highway when they encounter a massive "mothership" three times the size of a football stadium. Their description matches at least 30 other witnesses who see the same object in the sky that night around Fox Lake and the village of Pelly Crossing. It is one of the most extensively documented and researched UFO sightings in Northern Canada. Part 2: MISSILE MALFUNCTION: MARCH 24, 1967: Deputy Commander Robert Salas receives an mergency call from guards at the Malmstrom Air Force Base in Montana who have spotted an unidentified object overhead. In the 1960's, the base is the largest nuclear weapons complex in the world and is home to an arsenal of Minuteman Intercontinental Ballistic Missiles. As the object passes over the base, "all hell breaks loose" when the ten minuteman missiles suddenly go off line.
