Yesterday, we lost four members of our Arctic Warrior family and it's a loss felt across our entire joint installation. Right now, our immediate focus is on providing all possible support to the loved ones of our fallen aviators. We are also engaged in a deliberate investigative process."

A board of officers will investigate the accident, Orland said.
