For as long as humans have gazed at the night sky, they've seen things that cannot be explained. UFO HUNTERS examines some of the most intriguing sightings, from as long ago as nineteenth-century Texas to today. Bill Birnes and Pat Uskert, both from UFO Magazine, and Dr. Ted Acworth, who has worked for NASA and MIT, have unparalleled access to UFO evidence and can quickly identify bogus claims. Together they analyze eyewitness accounts, scientific experiments, declassified documents, and new television footage to separate fact from fallacy. Their goal: neither to prove nor disprove the existence of UFOs, but to accurately and methodically evaluate the evidence. In SEASON TWO of this hit HISTORY series, the team's investigations take them across Europe and North America, and include a fresh look at Roswell, New Mexico.The truth is out there - and the UFO HUNTERS are on the case.
