TUCSON, Ariz. (KGUN) — Davis-Monthan Air Force Base had a celebration Wednesday that carried some sadness too. The A-10 Warthog, which has been the heart of the base is going away from Tucson and being reassigned to other places. Pilots flew two A-10s in farewell flights over the base, showing the tight turns that made the plane so good at staying close to its targets. Davis-Monthan has been home to the A-10 and the center of A-10 pilot training since the first planes arrived more than 50 years ago. Current A-10 Pilot Major Duck Yim says protecting soldiers on the ground is the main reason he wanted to fly the Warthog.
