Colony Glacier is a real world mission to recover the remains and wreckage of a U.S. Air Force C-124 Globemaster aircraft that crashed Nov. 22, 1952, near Mt. Gannett, Alaska. Soldiers assigned to the Alaska Army National Guard discovered the debris from a Blackhawk helicopter on June 10, 2012, during a routine training mission on Colony Glacier nearly 14 miles from where the plane first crashed.
