The Alien Files

In this first episode of The Alien Files: UFOs Under Investigation, experts examine the history of UFOs, the validity of so-called UFOlogists and what the future will bring for UFO chasers.

There are hundreds of so-called religious groups across the world headed by leaders pretending to be in contact with superior beings from outer space.

Fixed photographs, fake flying saucer crashes, cosmic messages, film-segment showing the alleged autopsy of an extraterrestrial...this episode looks at some of the most famous masterstrokes of the kind.

Silence, cover-ups, formal denials, disinformation...anything goes when it comes to hiding the truth from the general public.

In most cases, UFO sightings are easily explained by simple scientific facts: optical illusions, atmospheric phenomena, sounding balloons, hallucinations.

Many spectacular UFO sightings across the USA, Canada, Europe or South America have remained unexplained despite serious and thorough investigations.
