A U.S. Air Force F-35A Lightning II pilot from the 33rd Fighter Wing closes the gap between the jet and the KC-135R Stratotanker for an aerial refueling during Exercise Savannah Shift, Savannah, Georgia, Sept. 21, 2020. Aerial refueling allows aircraft to remain in the air longer and extends the pilot’s range. (U.S. Air Force photo by Senior Airman Heather LeVeille)
