OSAN AIR BASE, Republic of Korea -- The tight working conditions inside of the A10c Thunderbolt present a challenge. Airmen with the 51st Maintenance Squadron are required to be prepared for scenarios involving an incapacitated worker that needs to be rescued from the fuel compartment. Fuels technicians practice these procedures in a confined space annually to ensure that if a situation involving an incapacitated Airman occurs, all personnel will be prepared.
