Alaska State Troopers say that four people were critically injured in a plane crash Sunday near the summit of Atigun Pass in the northern part of the state.
The Alaska Dispatch News reports that the troopers say Alyeska Pipeline Service Company security guards first reported the crash about 1:45 p.m.
Alaska State Troopers spokeswoman Beth Ipsen says the plane was reported to have crashed near mile 243.5 of the Dalton Highway.
The four injured are believed to have been the only people onboard.
The Dispatch News reports that it’s unclear if the injured passengers had been taken to a hospital Sunday evening. Ipsen says the crash happened in the North Slope Borough.
Clint Johnson, the head of the National Transportation Safety Board’s Anchorage office, says the agency is investigating.
