A camouflaged Sikorsky HH-3E "Jolly Green Giant" sits on the ramp at a Vietnam-era air base. Distinguished by its boat-hull fuselage and sponson-mounted fuel tanks, this twin-engine helicopter was flown by Air Force Air Rescue and Recovery Squadrons to retrieve downed aircrews, often deep in hostile territory. A ground crewman walks past the nose while support equipment stands ready nearby, a routine scene from the daily operations that kept rescue helicopters mission-ready throughout the war.
