ALASKA'S BERMUDA TRIANGLE

In Alaska, people, planes and ships disappear--suddenly, inexplicably and permanently.Of course ,in an enormous territory with lots of difficult terrain and shifting weather, this is not entirely surprising.

ALASKA'S BERMUDA TRIANGLE investigates this phenomenon, focusing on one case in particular, the 1972 disappearance of a plane carrying two U.S. congressmen.
