The Tybee Bomb is a 7,600-pound (3,500-kg) nuclear bomb containing 400 pounds (180 kg) of conventional high explosives and highly enriched uranium. During a simulated combat mission, the B-47 bomber carrying it collided with an F-86 fighter plane, and the bomb was jettisoned and lost. It is presumed to be somewhere in Wassaw Sound, off the shores of Georgia's Tybee Island, but recovery efforts have been unsuccessful. In 2004, a retired air force pilot made what discovery in the case? Discuss (http://forum.thefreedictionary.com/postst73467_Hydrogen-Bomb-Lost-in-the-Ocean.aspx)
