One of my favorite shows, this was a great episode where they searched for aliens/ufo's in Chile. They found an unidentified corps and what I think is even better, caught a UFO on film in the middle of a desert.....oh, and the UFO gave a noise that there equipment that wasn't plugged in picked up. Def worth watching. Part two is the actual evidence they find, but part one is the lead in.
