When Hurricane Michael, a Category 5 storm, tore through Florida's Tyndall Air Force Base in 2018, it battered F-22 stealth fighter jets, destroyed hundreds of buildings and churned up 700,000 cubic yards of debris. The total cost of the damage approached $5 billion. Now, Tyndall is being rebuilt as a super-resilient "installation of the future." New buildings sit more than a foot above the ground, to remain dry through 75 years of sea-level rise.
