Lee, Fifteenth AF command chief, watch a demonstration of the stormwater pumping station at Joint Base Langley-Eustis, Virginia, Dec. 1, 2021. Koscheski was briefed by members of the 633d Civil Engineer Squadron about challenges posed by recent storm surges. Base visits like these allow senior leaders to interact with service members to see first-hand some of the successes and challenges faced at different installations across the Air Force.
