Amazing story (WWII)

My Grandfather was a WWII veteran, member of the 509th Composite Group, 603rd Air Engineering Squadron, "Atom Boys". Part of the Manhattan Project. Worked on the top secret mission that Secured the atomic bombs and the B29 that delivered them on Tinian Island. He was part of history and an integral part of what made this country great. I am proud to be his grandson but unfortunately never got to meet him as he died at 53 years of age in November of 1968 while his son, my father, was fighting another war in Vietnam.
My father was a decorated combat veteran, US Army 1st Cavalry Division, 2nd Battalion / 5th Cavalry (Sergeant). Although he didn't speak about it often, and rarely hinted at the things he saw and did specifically, he did convey that war is a terrible thing to have gone through, and that they were just kids. He passed away a month ago at 67 years of age. He was proud of his country and his service to it. And I am proud to have been his son.
Thank you to all of the Veterans in this group and beyond. Your service has not gone unappreciated!
