The PBS series NOVA recently premiered an episode entitled "What are UFOs?" and we have it here for you to watch in its entirety. Though it presents a somewhat skeptical analysis of the military sightings of recent years, including Gimbal, 'Tic Tac,' and Aguadilla with debunkers like Mick West, the episode also acknowledges some of the genuinely enigmatic aspects of the phenomenon, and how the science often remains inconclusive.
