America lost a bomb. I’m not kidding. Sixty-two years ago, today, the United States Air Force dropped a nuclear bomb in the water off the coast of Tybee Island, very close to Savannah, Georgia. A North American Aviation F-86 Sabrejet fighter plane and a Boeing B-47 Stratojet strategic bomber collided during practicing exercises and, in fear of a detonation in the event of a crash, the crew jettisoned the bomb. They still haven’t found it and it is assumed to be somewhere at the bottom of Wassaw Sound.

Midair Collision:

The B-47 bomber was on a simulated combat mission from Homestead Air Force Base in Florida. It was carrying a single 7,600-pound bomb. At about 2:00am EST, an F-86 fighter collided with the B-47. The F-86 crashed after the pilot ejected from the plane. The damaged B-47 remained airborne, plummeting 18,000 feet from 38,000 feet when [the pilot] regained flight control. The crew requested permission to [drop] the bomb in order to reduce weight and prevent the bomb from exploding during an emergency landing. Permission was granted and the bomb was jettisoned at 7,200 feet […]. The crew did not see an explosion when the bomb struck the sea. They managed to land the B-47 safely at […] Hunter Air Force Base. The pilot, a Colonel Howard Richardson, was awarded the Distinguished Flying Cross after this incident.

The Bomb:

Some sources describe the bomb as a functional nuclear weapon but, others describe it as disabled. If it had a plutonium nuclear core installed, it was a fully functional weapon. If it had a dummy core installed, it was incapable of producing a nuclear explosion but, could still produce a conventional explosion. […] The Air Force maintains that its nuclear capsule, used to initiate the nuclear reaction, was removed before its flight aboard B-47. […] the bomb contained a simulated 150-pound cap made of lead. However, according to 1966 Congressional testimony by Assistant Secretary of Defense W.J. Howard, the Tybee Island bomb was a “complete weapon, a bomb with a nuclear capsule” and one of two weapons lost that contained a plutonium trigger. Nevertheless, a study of the Strategic Air Command documents indicates that Alert Force test flights in February 1958 with the older Mark 15 payloads were not authorized to fly with nuclear capsules on board.

The collision, and its aftermath, also drives the plot of the novel Three Chords & The Truth by Craig McDonald, published in November 2016.

    Whoops! Where did that bomb go?
    Do they look for it now? Looks like they could find it with the technology they have now.

      I think the last time they tried was 2004, 2008… They used a Geiger counter but, found the radiation occurring naturally. Plus, equipment costs time and money…and it would be an embarrassment for the Air Force, again. As long as people aren’t dropping dead from radiation sickness in the bay, no one is going to look for it.

        Just people being born with 3 eyes…no but could it still explode? I would think it could.

          Could it still explode? Good question. It’s been in the sea for 62 years with salt water working on it. There are ancient shipwrecks found with hulls mostly intact. How many years would it take for sea water to eat thru whatever metal it’s made of? Past that, would sea water interact with the nuclear part? The Air Force wasn’t very forthcoming with whether or not it had a lead plug or a plutonium detonator. When it was dropped, it didn’t go boom.

          I do know that C4 will not explode without a detonator. You can light C4 and heat food with it. Ken has done that.

          Sweet. I’ve been a shopping fool, today.
