Airman Grantham Dorriety, left, and Airman Gregory Herrera, 364th Training Squadron electrical and environmental systems apprentice course students, remove a backup bleed air valve at Sheppard Air Force Base, Texas, June 14, 2019. The backup bleed air valve controls the air pressure for the air conditioning unit in the flight-deck, without proper air pressure the pilot could pass out. Once the students remove the valve they will learn how to re-install it. (U.S. Air Force photo by Airman 1st Class Pedro Tenorio)
