Perhaps the best one I have seen to date.

Inside Hangar 1, MUFON archives contain dozens of reports of UFO crashes–yet few of these incidents ever reach the public. In 1976, a UFO crash along the Gulf of Mexico leads to a confrontation between the U.S. and Mexico, with a deadly aftermath. In the 1800s, a small farm town holds a public funeral for an extraterrestrial pilot of a crashed flying saucer. And in Kecksburg, Pennsylvania, one man's search for the truth behind a 1965 UFO crash may have led to his murder. Who is covering up evidence of UFO crashes, and how far will they go to keep you from knowing the truth?
