Senior Airman John Wilson prepares an E-3 AWACS at Tinker Air Force Base, Okla., in 2012 for its first flight since the plane was upgraded with the Block 40/45 modification. Hanscom AFB’s program office is the lead integrator and recently met a significant milestone for the upgrade, which is the biggest in AWACS history, replacing mission computer systems and infrastructure with modern, user-friendly and net-centric advancements. Wilson is with the 552nd Aircraft Maintenance Squadron. (U.S. Air Force photo/Margo Wright)
