Throttles make it go
The throttles of a 92nd Air Refueling Wing KC-135 Stratotanker from Fairchild Air Force Base, Wash., enable pilots to control the aircraft’s four massive CFM International CFM-56 turbofan engines on the way to exercise AMALGAM DART 15-2 at Eielson AFB, Alaska, May 27, 2015, over British Columbia, Canada. The KC-135’s engines each produce 21,634 pounds of thrust propelling the aerial refueling and airlift aircraft at speeds up to 530 miles per hour at 30,000 feet. Fairchild AFB, Wash., and McConnell AFB, Kan., KC-135s joined approximately 300 military personnel and 15 aircraft in exercise AMALGAM DART 15-2 May 26 through June 1.
