So here's a story that honestly keeps me up at night.
Picture this: It's December 1965. The Vietnam War is heating up, and the USS Ticonderoga—an aircraft carrier that had seen action in World War II—was heading back to Japan after another round of bombing missions over North Vietnam. On paper, this was supposed to be just another routine day. But routine, it turns out, is a dangerous word when nuclear weapons are involved.
The crew was running a standard exercise: loading and unloading a B43 nuclear bomb onto a Douglas A-4E Skyhawk attack jet. This thing wasn't a toy—it was a thermonuclear weapon with a yield of up to 1 megaton. For reference, that's roughly 70 times more powerful than the bomb that devastated Hiroshima. The kind of device that could level a city in the blink of an eye.
Chief Petty Officer Delbert Mitchell was there that day. He remembered it like it was yesterday when he spoke to the U.S. Naval Institute years later. His team had checklists for everything—six people, each watching their specific task. His job? Make sure the weapon was on "safe" and report back to the crew chief. When they pulled off the gray tarp covering the bomb and saw the "Y1" marking, Mitchell said his heart just sank. They all knew exactly what they were dealing with.
They used a specialized hydraulic truck to lift the nearly 2,100-pound bomb into position beneath the Skyhawk, locked it in tight, and watched as the aircraft was pushed onto the No. 2 plane elevator. That's when things went sideways—literally.
Here's the thing about the Ticonderoga that most people don't know: this carrier had a deck-edge elevator. Instead of having elevators in the center of the ship like most carriers, the No. 2 elevator stuck out from the side of the hull, cantilevered over the ocean. One entire side was completely open to the sea. Sure, there was safety netting to keep crew members from falling in, but that netting was definitely not designed to stop a nearly-one-ton aircraft from rolling off.
The ship turned to starboard. And when it did, the deck tilted—and so did the elevator platform. Suddenly, the Skyhawk with its nuclear payload was on a slight slope, angled directly toward that unprotected edge. Crew members blew their whistles frantically, trying to warn the pilot, Lieutenant Douglas Webster. But for some reason—maybe he was distracted, maybe he was searching for something in the cockpit—he didn't seem to notice.
And then... it was over. The Skyhawk rolled off the edge and plunged into the Pacific Ocean. The weight of that bomb pulled everything down fast. Nobody had time to react. The aircraft, the pilot, and the most dangerous weapon you can imagine—all of it sank like a stone, approximately 68 miles from Kikai Island in Japan.
That was 61 years ago.
And here's the truly unsettling part: they've never found it. This megaton-class nuclear bomb is still sitting somewhere at the bottom of the Pacific Ocean, and as far as I know, nobody has any concrete plans to go looking for it.
I don't know about you, but when I read stories like this, I find myself wondering about the sheer number of close calls, the human errors, and the absolute miracle that we don't live in a much scarier world. Someone loaded a city-killer onto a jet, watched it roll off the side of a ship, and that was that. Life went on. The carrier continued its mission.
Maybe that bomb will sit down there forever, a quiet reminder of how fragile our systems really are. Or maybe someday, someone will decide it's worth the trouble to fish it out.
Until then, it's just... out there. Waiting.
