This major four-part series made by Four Winds for the Discovery Network presents all the credible scientific evidence in the UFO debate. It is an antidote to the widespread perception of viewers that UFO reports are either hoaxes or genuine alien contacts.

UFOs: Down To Earth shows how natural phenomena, top-secret technology, altered states of the mind and mythology all provide much more realistic explanations for supposed encounters with aliens. However, the series is not afraid to look at those reports for which there is no easy explanation.

The series features or used as advisors many talented and experienced UFO, black technology and and paranormal investigators including Greg Long, Curtis Peebles, Jenny Randles, Barry Greenwood, Andy Roberts, Bill Sweetman, Steve Douglass, Warren James, Tom Mahood and many others.
