WWII pilots who survived crash into Greenland glacier
On November 5, 1942, an American C-53 cargo plane on a routine mission in World War II crashed into a glacier in Greenland. Incredibly, all five men aboard survived.
Four days later, a B-17 bomber searching for the C-53 also went down in a blinding storm, leaving nine more men stranded in the Arctic.
A third plane was sent to rescue the survivors of the B-17 crash. After one successful attempt, it too disappeared into the snow.
When rescues were called off for the winter, the survivors of the B-17 were forced to find a way to survive for five months living in the tail of their plane, which had ripped in half. They faced temperatures of -40C and were surrounded on all sides by deadly crevasses.
In Frozen in Time, Mitchell Zuckoff recounts their harrowing experiences as well as a modern expedition to find the remains of one of the planes and its crew, still missing 70 years later.
