NOVA follows an adventure to try to retrieve an almost intact B-29 from the Arctic Circle. The airplane crash-landed nearly 50 years earlier during a secret mission for the U.S. The pilots survived the crash and were rescued, but the B-29 was left in the harsh and unforgiving climate 250 miles north of Thule, Greenland. Battling unpredictable weather, an unforgiving landscape, limited equipment, illness and fatigue, pilot Darryl Greenamyer and his team rush to refurbish the plane before the harsh winter sets in.
