He joined the navy when he was 14, served durign WWII, then went home and finished high school. He then joined the army and fought as an infantryman (he was an engineer) at Porkchop Hill and was one of only a few14-30 effectives of K and L 31st infantry and G company 17th Infantry companies. It during this this battle where he earned a battlefield commission.
He didn't just fly out wounded, he flew in supplies and kept the US troops supplied so they could fight back. That probably saved more American lives than the medevac actions. He retired in 1967 as a master aviator but only had the DSC. He would not be awarded his CMoH for a couple of decades, Bush 43 would drape that pale blue ribbon around his neck on him in 2001.
By the time he stopped flying at all he had 25,000 hours, 8,000 fixed wing and 17,000 rotary.
