U.S. Air Force Senior Airman Jordan Arnold, 325th Aircraft Maintenance Squadron crew chief, from Tyndall Air Force Base, performs final checks on an F-22 Raptor during a rapid crew swap at Eglin AFB, Florida, July 2, 2019. Hot-pit refueling coupled with rapid crew swaps reduces the amount of time it takes to get a new pilot in the air, saves time and produces more sorties with less aircraft.
