NASA's unexplained files -- The aliens have landed -- Killer aliens.
Mysterious flying objects, unexplained disappearances, species invasions: a swirl of suspicion has circled our planet for decades, but few definitive answers have been offered. This collection combs through three and a half hours of evidence, interviews, and theories that attempt to explain the unexplained. From astronauts to abductees, a variety of sources submit film footage and firsthand testimonies to be examined in search for the truth.
