ANCHORAGE, Alaska — A man suffered serious head injuries when he was struck by an airplane taking off from ice in Alaska's Beaufort Sea during Navy exercises.
The civilian employee of the Navy's Arctic Submarine Laboratory is expected to recover.
Anchorage television station KTVA reports the man was at the base camp on March 20 for Ice Exercise 2018, also known as ICEX.
The Navy used the camp 140 miles (225 kilometers) north of Deadhorse to coordinate submarine exercises.
A National Transportation Safety Board preliminary report released Tuesday says a de Havilland DHC-6 Twin Otter operated by Homer, Alaska-based Bald Mountain Air Service struck the man as he photographed the airplane.
The injured man was flown to Anchorage. ICEX has concluded but the $2.5 million damaged plane remains on Arctic sea ice.
