For close to a half century, Luke Air Force Base near Phoenix, Arizona, was the main training center for U.S. Air Force F-16 pilots. But on September 30, the last Fighting Falcon training mission closed out that history. The Air Force announced this week that the 56th Fighter Wing has now shifted exclusively to flying F-35A Lightning II combat aircraft. Programs will be updated, infrastructure remodeled, and F-16 support equipment dismantled to make way for the new stealth fighters.
