I have a couple, and they aren't experiences from band camp.
They also aren't all of them, but they're the ones that come immediately to mind as I've had a few beers.
I was an air traffic controller for my first enlistment, and then intel for the rest of my twenty in the USMC. This is in a rough timeline from 1974 to present.
Pohakaloa Training Area, Hawaii (PTA for you Army types)
-AH-1 slams into hillside due to high winds. Pilot dies of cardiac arrest and gunner severely burned.
Kaneohe Bay, Hawaii
- CH-46d loses front rotor and crashes on the 101 pad. All die.
MCAS Tustin, CA
-CH 46e and CH-53d collide in mid air in the pattern. All die except the crew chief of the CH-53.
South Korea circa 1983
- I watch a North Korean SOF team get wiped out near Ulsan Nuclear powerplant as they try to exfil South Korea. I was on a ship and not involved, but I could see it.
Above the Arctic Circle near Norway
- CH 46e overloaded with guys from Charlie 1/6 depart the USS Saipan. Bird has problems and slams down on the deck directly above my head. Bounces off flight deck and into frigid water. We can see survivors, but they are dying from the intensely cold water, and we can't get to them in time. I don't recall how many died, but I want to say around twelve. The movie "Titanic" gives me the creeps when it shows the human popsicles in the water after the collision, and I later see similarities with our tragedy.
I encounter a head on collision on NC Highway 19 coming from the Camp Lejeune rifle range as I travel north towards Jacksonville at about 0200. I see two cars upside down. Three old ladies are in one and as gray as they can be (their flesh, not their hair. They had just had a head on with a drunk driver who was a civilian insurance adjuster. I don't know if they made it, as there was never anything in the press. If it was a jarhead, there sure as hell would've been a front page story about it.
While in Okinawa, a guy from 2/3 puts a round from an M-60 through the chest of the armorer when turning in the weapon. I did not see this, but I was in the 1/6 advance party replacing 2/3, and I had to endure the same shit/after-effects their staff was dealing with from the Bn commander for such a fuck-up.
I was doing an operation with either 5th or 7th SFG (don't remember) and they Halo'd into a high tension wire near Yuma Proving Ground (YPG) at a place you Army guys may know as prep for Desert One. He was lifeflighted to Phoenix but died of cardiac arrest.
Although I didn't see this, I was part of the investigation into the death of a USC in Redford TX. Look it up. It's way too long to go into.
The other stuff I can't get into, but it sucks way worse than this and you would probably be pissed if you knew.
