The crew made an unauthorized deviation from the airway, trying to reduce distance on a 'dog-leg' of the airway. The DC-3 collided with Elk Mountain 340 feet below the crest, at an elevation approximately 180 feet below its assigned cruising altitude (11,000 feet) and 4 1/2 miles south of Airway Green 3.
PROBABLE CAUSE: "The deviation from the prescribed route at an altitude insufficient to assure adequate clearance over Elk Mountain."
