Secrets of Ancient Structures

Across the globe and throughout history, ancient civilizations erected structures that continue to inspire awe and wonder; archaeological finds and new technologies reveal clues to long-enduring mysteries.

Air Warriors

"Air Warrriors" puts the spotlight on some of the airplanes that have been used by American forces in combat battles through the years. The program profiles the dedicated pilots and other team members who fly and maintain the aircraft. Rarely seen combat footage and pilots' stories help bring to life the journeys that have been taken by the flying machines, which include a plane-chopper hybrid that saves lives and an attack helicopter that is called the Black Death by America's enemies.

America's Book of Secrets

"I could tell you, but then I'd have to kill you." That cliche apparently doesn't apply to this series that reveals what goes on behind the scenes of some of America's legendary monuments and powerful organizations, with some inside information that has previously been withheld from the public. If you've ever wondered what goes on at the FBI or Fort Knox, this is your chance to learn about them. And what about Area 51? You'll also learn information about that infamous military base (and maybe more?). "America's Book of Secrets" is your chance to go beyond locked doors and security checkpoints to see things that you were never intended to see.
