A school chum of my mom’s lost her husband flying helos, I believe, for the 101st Airborne very early on. Guess I was fortunate in knowing a lot of people superficially who went and came back from Vietnam – something somewhat more certain for most in the Air Force except aircrew and security police I suppose. There was only one person I knew somewhat at a personal level who I heard was lost later was our neighbor across the hall in housing when we arrived in Germany, who flew C-130s around Europe. He volunteered for Special OPs and went to Thailand, where he flew on 16th Spec Ops AC-130 missions over Laos/Ho Chi Minh Trail/etc. He was the fire control officer on “Thor” when it was shot down over the Trail just before Christmas 72. Two lucky survivors out of a crew of 18 or so IIRC and Bob wasn’t one of them.
