Seventy-four years ago, an American B-24 Liberator bomber known as the Tulsamerican fell from the sky while returning from a mission over Europe and disappeared beneath the waves of the Adriatic Sea. Seven crew members survived the crash and were rescued. Three men were never found - thought to be lost forever, unrecoverable.
Now, NOVA, produced by WGBH Boston, joins the U.S. Department of Defense, the Croatian Navy, and an elite team of underwater archeologists and technical divers as they excavate the wreckage of a WWII icon: the last B-24 ever built in Tulsa, Oklahoma, and paid for by the factory workers. Using science to unlock the mystery, the group embarks on a deep and dangerous expedition, racing the clock to determine what happened to the missing airmen, with the hope of finally bringing them home.
