U.S. Air Force Thunderbird Refuel
The U.S. Air Force Thunderbirds fly the Delta formation over Louisiana Feb. 19, 2016. The Thunderbirds were refueled twice by a KC-135 Stratotanker from MacDill Air Force Base, Fla., once over New Mexico and a second time over Louisiana on their way to Daytona Beach, Fla., for their Daytona 500 flyover.
