F-16s from the 140th Wing, Colorado Air National Guard begin to return to Buckley Air Force Base July 12, 2014, slightly ahead of schedule, after spending approximately three months at Denver International Airport while the base runway was being reconstructed. Despite relocating their entire flying operations, the wing managed to provide uninterrupted support to their Aerospace Control Alert mission 24/7 throughout the transition to DIA and back to Buckley AFB.
