Through the Fog, US Army Photo

An instructor pilot walks onto the flightline while maintenance crews inspect at UH-60M Black Hawk helicopter at Lowe Army Heliport, Fort Rucker, Ala. in a dense fog that blanketed lower part of the state for several hours on the morning of May 9, 2013. Maintenance of existing equipment is crucial to keeping operating costs low for the multi-functional aircraft that has been used around the world for the past three decades.
