MINOT (AP) - The Air Force says B-52 crews from the Minot Air Force Base have been part of a 10-day training exercise from Guam to Alaska.

Officials say the B-52s flew nonstop from Guam and Louisiana to the Pacific Alaska Range Complex, where they simulated dropping their payloads.

About 300 airmen from Minot base's 5th Bomb Wing currently are deployed to Guam as part of a four-month rotation.

Col. Parker Northrup III is the commander of the 5th Operations Group at the Minot base. He says crews from the base are involved in missions all the way from Alaska to Australia and throughout the Pacific Rim.

Northrop says the crews face different maintenance challenges because of the different climates. He says they're not used to "86 degrees every day for five months."
