There's Bombs In Them Thar Swamps

Well one bomb anyway, but it's a big one.  It seems that in 1961 the Air Force managed to let a couple of nukes drop in the Nahunta Swamp near Goldsboro, NC.  The pilot was only following procedure, his bomber having lost a wing in a storm.  One of the nukes wafted down on a parachute and the military picked it up quickly.  The other one, well it's still down in the muck somewhere...

The one they got back.

Good thing they didn't go off, we wouldn't be able to stop at Wilbur's on the way to the coast if they had...
