There was a rumor on a local radio station that Luke AFB might become a training facility for one of the new generation jet fighters coming online. Joint Strike Fighter? I don’t recall the details, but it makes sense. The locals and the state have been making laws to prevent “encroachment” on the facility so it can continue to operate.
One of the most stupid things I can think of when a community develops all around close to a base, gets tons of noise complaints, then whines when the base closes. Many of those bases have been flying planes or doing other operations that "intrude" on the local communities out of those locations for decades, some for over a century. Many of those bases were built in sparsely populated areas to prevent this very problem.
