Unmanned F-16 jets are flying again at Tyndall Air Force base on Florida's Panhandle, and for many it's a welcome sound. Four months ago the base took a direct hit from Hurricane Michael. The storm's 155-mile-per-hour winds toppled forests, shredded buildings and left the base a mess with its future in doubt.
Now the Air Force says it is rebuilding Tyndall to be the air base of the future. Officials say the rebuilt base will be resistant to storm surges and to wind speeds up to 180 miles per hour and is expected to cost some $3 billion.
Tyndall is one of the nation's largest Air Force bases and is in a key location, next to the Air Force's testing and training range over the Gulf of Mexico. But that location also put it in the path of one of the most powerful hurricanes ever to hit the continental U.S.
