PBS's NOVA on Tuesday launched a companion Web site to accompany "Hitler's Sunken Secret," a television special that aired the same day. The documentary follows explorers 1,300 feet beneath a remote
Norwegian lake as they search for a ferry sunk during World War II. The site--www.pbs.org/nova/hydro--features the only known Nazi diagram of a nuclear weapon, and new information about how near the
Nazis were to developing their own weapon; a slide show of the spy messages; related links, books, and a teacher's guide.
