A C-130J Super Hercules aircraft from the Kentucky Air National Guard’s 165th Airlift Squadron lands at Barkley Regional Airport in Paducah, Ky., May 13, 2025, carrying Airmen and equipment needed to stand up an aerial port that will function as a cargo hub and evacuation center as part of Exercise Grindstone, a major earthquake-response simulation. Paducah lies within the New Madrid Seismic Zone, the most active seismic area in the Eastern United States, and could serve as an air hub in the event of an large-scale earthquake (U.S. Air National Guard photo by Dale Greer)
