Sikorsky HH-3E 'Jolly Green Giant' rescue helicopters sit on the flight line at a Southeast Asian airbase during the Vietnam War. Equipped with a nose-mounted refueling probe for extended-range missions, the HH-3E was the primary long-range combat search-and-rescue helicopter flown by USAF Aerospace Rescue and Recovery Service crews before the arrival of the larger HH-53 'Super Jolly.' Background signage identifies this as a Jolly Green Giant rescue squadron's home base. Project: 218965
