In this episode we go on board with a Japanese Airlines cargo plane over north-eastern Alaska, as it is seemingly followed by UFOs at 35,000 feet. The incident sparks an FAA investigation and claims of secret involvement by the FBI and CIA. We also travel to Westall, a town on the outskirts of Melbourne, Australia. In April 1966, this unassuming suburb was home to a mass daylight sighting of a UFO. Finally, we explore a bizarre series of UFO sightings in a remote town in northern Peru. The incidents, caught on video by a local photographer, spark off an investigation by a newly formed government department.
