Not too many families had a nuclear bomb dropped in their backyard, and survived. The Gregg family of Mars Bluff, South Carolina, was one of them.

On March 11, 1958, a group of four U.S. Air Force Boeing B-47E-LM took off from Hunter Air Force Base in Savannah, Georgia. They were heading to England to take part in a mission called Operation Snow Flurry, where they would perform mock bomb drops. This was a time when the Cold War was in full swing, and Air Force bombers, such as the ones taking part in Operation Snow Flurry, were issued a MK 6 nuclear bomb each that were to be carried onboard in case the planes needed to activate during an emergency wartime situation.
