Lloyd, if we are talking about the same incident, it was 4-15-68 and the Sr. Medic was Sp5 James Thomas McMaster. I helped work on him with several others until the dustoff got there. We could still hear the chopper in the distance when they called back and told us he didn't make it. He was cooking with c-4 and they zeroed in on that bright flame. He is listed in 4/31 HHC honor roll.
