Fuel tank repair everywhere
U.S. Air Force Airman 1st Class Grace Mathews, 355th Component Maintenance Squadron fuel system journeyman, enters the inside of an A-10 Thunderbolt II fuel tank while her attendant watches over her at Davis-Monthan Air Base, Arizona, Sept. 17, 2019. Mathews was tasked to scrape sealant off the inside of the fuel tank to prepare it for further maintenance. While she accomplished this, the attendant was in charge of walking her through the next steps and ensuring her safety. (U.S. Air Force photo by Senior Airman Cheyenne A. Powers)
