Around the 3:00 mark, he starts talking about UFOs in Vietnam, and around 3:55, he says the words "enemy helicopter activity" used in communications
in Vietnam referred to UFOs.
Now, I never paid any attention to the Vietnam War in History class (cuz i didn't wanna), but I'm pretty sure there were not any helicopters used by
the enemy in Vietnam. Does anybody have any more information on this and possibly any videos showing communicators using the words "enemy helicopter
activity"? Also, if this has been posted before, please forgive me. So much stuff on this board, it's hard to tell what has been covered already.
