Certainly one of the "iconic" aircraft of the Vietnam war. Am surprised there are so few remaining…unless you specifically mean the UH-1H variant…since they are still widely flying in the USMC and elsewhere…I think.
Yes sir, you are correct - I specifically meant the UH-1H variant, and specifically in US Army service. There are three airworthy airframes in Huntsville, three at White Sands, and three at another location I forgot about.. The Army has massive parts warehouses at all three and they are very affordable test platforms flown by a contracted pilot/ crew chief team. I wanted to pitch a "last Huey's in the Army" photo essay to a friend with magazine connections, but he said that there have been so many 'last Huey' stories over the years that magazine editors are burned out on them - they always find another obscure unit somewhere flying a UH-1..
Our local airport manager called his father to come out to see the aircraft while the crew was at lunch. He flew the Huey (UH-1D?) from 1967-1969 in Vietnam as a young Army officer and amassed over 1000 hours flying. He said that since they had a small side armor door, the crews oftentimes took their chicken plates off and laid them underneath the rudder pedals over the glass in order to protect themselves from ground fire. Another story he told was that a South Vietnamese soldier (a VC sympathizer) was being taken in to a hot LZ, and after dismounting from the aircraft he turned around and hurled a grenade back into the Huey killing the crew and destroying the aircraft. After that, his command dictated that they brief all their passengers not to turn around or even even look back as they exited the aircraft or else the door gunners would shoot them. Apparently it worked, as it never happened again.
He was just leaving Vietnam as the UH-1H was introduced into service in his area, but after examining the aircraft he said that "it still looks exactly the same".
