JOINT BASE ELMENDORF-RICHARDSON - The North American Aerospace Defense Command is planning training exercises this week in southwest Alaska.
The training is scheduled for Wednesday. Officials say NORAD's geographical component, the Alaskan NORAD Region, also will take part in the training to practice interception and identification procedures.
NORAD is a joint U.S.-Canadian command that patrols the skies over North America. It is based at Peterson Air Force Base in Colorado.
