ANDERSEN AIR FORCE BASE, Guam- The engine throttles of a B-52 Stratofortress are tested after take-off to help ensure the mechanical life and stability of the engines are maintained, March 15 here. The pilots set the engines at different speeds and take the measurements on the panel, allowing them to see if the engines are performing at the same rates.
