A U.S. Air Force F-15E Strike Eagle aircraft assigned to the 391st Fighter Squadron sits on the flightline during sunset at Mountain Home Air Force Base, Idaho, Dec. 6. With a digital electronic engine control system, Strike Eagle pilots can accelerate from idle power to maximum afterburner in less than four seconds. Faster engine acceleration means quicker takeoffs and crisper response while maneuvering. (U.S. Air Force photo by Senior Airman Debbie Lockhart) (Released)
