1967
Unhh...this year was Super bowl 49 I believe, so 49 - 3 = 46 years ago was unh...1969, CTMay seemed awfully confident of 1967. I'll bet (s)he cheated. Dredging the memory to come up with USMA class of '68 had most members killed in VN. So, engineering estimate: 1967 - 1969.
I didn't cheat! I guessed and I got it wrong.
