I don't want to denigrate any heroics or disagree out of hand, but here are 'facts' from my fallible memory, six decades later with some Internet backup that reinforces:
Edited from https://www.nationalmuseum.af.mil - "The Air Rescue Service (later the Aerospace Rescue and Recovery Service) first used Kaman HH-43 Huskie helicopters, unofficially known as "Pedro" from their radio call sign. They later added larger Sikorsky HH-3 "Jolly Green Giant" helicopters, with greater range, and Grumman HU-16B Albatross amphibians to rescue Airmen who went down in the Gulf of Tonkin.
Air operations over dangerous enemy territory forced Search and Rescue (SAR) to evolve into Combat Search and Rescue (CSAR) teams. A major improvement came in November 1965, when the Sikorsky HH-53E "Super Jolly Green Giants" arrived. Capable of being refueled in flight, the HH-53E helicopters could reach any point in the Southeast Asia theater.
During the Southeast Asia War, CSAR personnel had a significant impact and lived up to their motto: "That Others May Live." They saved a total of 4,120 people, including 2,780 in combat situations. Their individual achievements earned them two Medals of Honor, 38 Air Force Crosses, and numerous other awards. However, the cost was high as 71 U.S. rescue personnel were killed and 45 aircraft destroyed during the war."
For some reason I was, and am, remembering Gary telling me "UH-1". I appreciate the correction and apologize for my misremembering.
