  • #3911 — Why Ships Sink
    Are you safe aboard a modern cruise ship? Twenty million passengers embark on cruises each year, vacationing in deluxe "floating cities" that offer everything from swimming pools to shopping malls to ice skating rinks. And the ships just keep getting bigger: The average cruise ship has doubled in size in just the last ten years. Some engineers fear that these towering behemoths are dangerously unstable, and the recent tragedy of the Costa Concordia has raised new questions about their safety. Now, NOVA brings together marine engineering and safety experts to reconstruct the events that led up to famous cruise disasters, including the ill-fated Concordia, the Sea Diamond, and the Oceanos. Are we really safe at sea-or are we on the brink of a 21st century Titanic?

  • #4112 — Escape from Nazi Alcatraz
    Colditz Castle, a notorious prisoner of war camp in Nazi Germany, was supposed to be escape-proof. But in the dark days at the end of World War II, a group of British officers dreamt up the ultimate escape plan: in a secret attic workshop, they constructed a two-man glider out of bed sheets and floorboards. Their plan was to fly to freedom from the roof of the castle, but the war ended before they could put it to the test. Now a crack team of aerospace engineers and carpenters rebuild the glider in the same attic using the same materials, and they'll do something the prisoners never got a chance to try: use a bathtub full of concrete to catapult the glider off the roof of the castle. As the hair-raising launch 90 feet up draws near, the program explores the Colditz legend and exposes the secrets of other ingenious and audacious escapes. Then, after a 70-year wait, the team finally finds out if the legendary glider plan would have succeeded.
