A U.S. Air Force HH-3E 'Jolly Green Giant' rescue helicopter sits on maintenance jacks, its rotor blades drooped and cabin doors open for servicing. Flown by Aerospace Rescue and Recovery Squadrons during the Vietnam War, the HH-3E's boat-hull fuselage, in-flight refueling probe, and rescue hoist equipped it to retrieve downed aircrew deep in hostile territory, often working in coordination with A-1 Skyraider 'Sandy' escort aircraft.
