According to reports the alarm was set off by some poor dude pushing the wrong button. On a much smaller scale I can relate to this guys misfortune. I'd like to share a story with you folks that happen about this same time in January 1968. I had just arrived at the Khe Sanh Combat Base and was setting up my stuff in the main Communication bunker which was a huge ugly hole in the ground with about a foot of water for carpet. This was about a week or so before the siege started and things were a little tense already. Anyway while getting all my crap stowed around all the comm gear I noticed a switch(unmarked) up high on a 12" by 12" timber support beam.Since it was pretty dark I figured it must be a light switch. Hell it looked like one so I turned it on. Guess what it was no light switch. I had just turned on all the warning sirens at Khe Sanh. In short order 8000 Marines were diving for cover expecting incoming rounds any second. I flipped the switch off immediately but the damage was done.About that time a Full Bird pissed off Colonel showed up. I just knew I would be hauled out and shot.The Colonel looked at me and looked at the switch. He then said that the thing looks like a light switch. With that I thought that maybe I would not be shot but just threw in the Brig for awhile. I caught hell for that one for a few days. The siege started a few days later and the matter was put to bed. Over the course of the next few months most of the sirens got blown away anyway. For a short time I had 8000 unhappy Combat Marines looking my way. Sort of humbles you in away. Maybe in 50 years that guy in Hawaii can share his story with some folks like all of you here and laugh about it.
