With over 7,500 hours investigating the D.B. Cooper mystery including analyzing evidence, interviewing witnesses, reading 20,000+ pages of FBI case files and exploring important locations, top D.B. Cooper expert, Eric Ulis, believes that he's found the true location where Cooper landed during his daring dive. Ulis has also assembled a team of specialists to explore the untouched Washington backcountry, federally restricted (wildlife refuge) land, to hunt for the missing evidence Cooper left behind. In addition, armed with new leads regarding the identity of Cooper, Eric works closely with a retired FBI agent as they set their sights on a living person of interest who could very well be the infamous D.B. Cooper as they attempt to solve the only unsolved skyjacking in United States history.

In 1914, Sir Ernest Shackleton led an expedition to Antarctica but soon after arrival, Shackleton's ship - The Endurance - was destroyed by shifting glaciers, and he was tasked with leading his 27 men across the tundra, on an epic struggle for survival. Shackleton's battle against the odds and his unfailing commitment to bring all his men out alive turned him into a legend that still inspires today. The Endurance is as illustrious as the Titanic, yet it has remained lost for over a hundred years. Its final resting ground remains as one of the greatest polar mysteries. Now, the HISTORY(R) channel follows a new ground-breaking expedition heading back into the frozen seas to hunt down the last piece of the story: Shackleton's lost ship. Led by maritime archeologist and shipwreck expert, Mensun Bound, this expedition is the result of two years of planning and over $250 million spent in cutting edge technology as they set out to break through the ice and locate this holy grail of shipwrecks.
