U.S. Air Force KC-46 Pegasus aircraft land on the runway at Altus Air Force Base, Oklahoma, during a large formation exercise, May 21, 2020. Altus AFB is located in Southwest Oklahoma and is prone to frequent severe weather events, which is why large formation exercises are important, so in the event of a real-world severe weather event, an evacuation can take place with less delays.
