On this special edition of America: Facts vs. Fiction, we open the nation's most secret vaults to separate fiction from fact at Fort Knox, the Federal Reserve Bank of New York, Cheyenne Mountain, and Iron Mountain Data Centers in Pennsylvania. And we take a trip along the sea of truth to expose the myths surrounding Titanic's final voyage and the Hindenburg's final flight.

Myths eclipse the real facts about NASA's dramatic rescue of three astronauts aboard the crippled Apollo 13 spacecraft; Hollywood movies have a hit-and-miss track record of depicting the realities of interstellar exploration.
