On a remote piece of land just outside of Florence, S.C., an atomic weapon was accidentally dropped on March 11, 1958.
Known as the “Mars Bluff Incident,” a sign on Crater Road acknowledges the accident, stating, “The bomb landed in the woods behind the asbestos-shingle sided home of a railroad conductor, Walter ”Bill“ Gregg. Gregg, his wife, their three children, and a niece were injured by the concussion, which destroyed the house and out-buildings and did slight damage to buildings within a 5-mile radius.”
