Invasion: Illinois

S2 E1: On August 21st, 2004, people driving home from an Ozzy Osbourne concert in Tinley Park, Illinois, reported seeing a large triangular UFO with three bright red lights. Two months later, on Halloween night, hundreds of eyewitnesses reported seeing a similar UFO. By the time the lights returned again the following year, the mountain of evidence was overwhelming--videos, eyewitnesses, and news coverage were everywhere. The team tackles this incredible contemporary UFO case, and searches for what's responsible for the mass sightings in a small Chicago suburb.
