The Unexplained

This documentary investigates the origins of the image of the flying saucer.

In the programme entitled "UFO - Reason to Believe" the question is posed: Are we alone in the universe?

In the programme "Down to Earth: Great Balls of Fire" the conflicting theories for and against the existence of UFO's are discussed. UFO sightings are most likely to occur at night, yet it is thought by others that these may, in fact, be simply electromagnetic activity. Also under question is whether or not alien abductions are a common neurological disturbance.
