It is the location of a hydrogen bomb lost by a B-47 Stratojet bomber in 1958. This lost hydrogen bomb is also known as the Tybee Bomb. On the night of February 5, 1958, a B-47 Stratojet bomber carrying a hydrogen bomb on a night training flight off the Georgia coast collided with an F-86 Saberjet fighter at 36,000 feet. The collision destroyed the fighter and severely damaged a wing of the bomber, leaving one of its engines partially dislodged. The bomber's pilot, Maj. Howard Richardson, was instructed to jettison the H-bomb before attempting a landing. Richardson dropped the bomb into the shallow waters of Wassaw Sound, near the mouth of the Savannah River, a few miles from the city ofTybee Island, where he believed the bomb would be swiftly recovered. The Pentagon recorded the incident in a top secret memo to the chairman of the United States Atomic Energy Commission. The memo has been partially declassified: "A B-47 aircraft with a nuclear weapon aboard was damaged in a collision with an F-86 aircraft near Sylvania, Georgia, on February 5, 1958. The B-47 aircraft attempted three times unsuccessfully to land with the weapon. The weapon was then jettisoned visually over water off the mouth of the Savannah River. No detonation was observed." Soon search and rescue teams were sent to the site. Wassaw Sound was cordoned off by United States Air Force troops. For six weeks, the Air Force looked for the bomb without success. 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. Then just a month later, the search was abruptly halted. The Air Force sent its forces to Florence, South Carolina, where another H-bomb had been accidentally dropped by a B-47. The bomb's 200 pounds of TNT exploded on impact, sending radioactive debris across the landscape. The explosion caused extensive property damage and several injuries on the ground. The weapon itself did not detonate. The search teams never returned to Tybee Island, and the missing H-bomb was declared lost. The end of the search was noted in a partially declassified memo from the Pentagon to the AEC, in which the Air Force politely requested a new H-bomb to replace the one it had lost. "The search for this weapon was discontinued on 4-16-1958 and the weapon is considered irretrievably lost. It is requested that one weapon be made available for release to the United States Department of Defense as a replacement." The bomb was again searched for in 2001 and not found. A new group in 2004 headed by Derek Duke claimed to have found an underwater object which it thinks is the bomb, but the US Army Corps of Engineers discounted the claim, saying the radioactive traces detected by the group were "naturally occurring". A satirical "news" website ran a story in February 2015 stating the bomb was found by vacationing Canadian divers and that the bomb had since been removed from the sound. The fake story spread widely via social media.
