80th Aircraft Maintenance Unit electrical and environmental personnel unload bleed air operations equipment at Kunsan Air Base, Republic of Korea, Nov. 6, 2020. Bleed air ops equipment checks the air pressure at different points on the jet to verify that the engine swaps over from high-stage to low-stage pressure, and to make sure proper airflow is getting to the cockpit and avionics equipment.
