"Tybee Island AKA Savannah Beach"

'The Tybee Island mid-air collision was an incident on February 5, 1958, in which the United States Air Force lost a 7,600-pound (3,400 kg) Mark 15 nuclear bomb in the waters off Tybee Island near Savannah, Georgia, United States. During a practice exercise, an F-86 fighter plane collided with the B-47 bomber carrying the bomb. To protect the aircrew from a possible detonation in the event of a crash, the bomb was jettisoned. Following several unsuccessful searches, the bomb was presumed lost somewhere in Wassaw Sound off the shores of Tybee Island.'

The Next Step Could Be Your Last

"Near Mt St Helens, in the Gifford Pinchot National Forest, and before the volcano erupted in 1980, there were areas where you were not allowed off the footpaths. This was because Douglas Firs, which can reach 200ft, were buried in ash in prior eruptions, then rotted away. So you could step on a relatively thin layer of old ash, break through, and fall any number of feet into what amounted to a crevasse or a well."
