Wassaw Sound is a bay of the Atlantic Ocean on the coast of Georgia, United States near Savannah at the mouth of the Wilmington River.
It was the location of an American Civil War naval battle between the CSS Atlanta and Union ships in 1863.
The collision destroyed the fighter and severely damaged a wing of the bomber, leaving one of its engines partially dislodged.
The Pentagon recorded the incident in a top secret memo to the chairman of the United States Atomic Energy Commission (AEC).
Underwater divers scoured the depths, troops tromped through nearby salt marshes, and a blimp hovered over the area attempting to spot a hole or crater in the beach or swamp.
