In the foggy, early evening of November 7th, 1990, two people at a Montreal hotel noticed something bizarre in the sky. Soon, multiple people in the hotel had gathered on a rooftop terrace to observe a genuine UFO -- and, soon after that, people across the city began reporting the object (if it was an object). In the almost three decades after this sighting, numerous witnesses, experts, fringe researchers and skeptics have attempted to explain exactly what was hovering over the sky for hours that evening. Join the guys as they delve into the case in tonight's Classic episode.
