“Days after the inauguration of John F. Kennedy in 1961, the American military came within a ‘hair’s breadth’ of detonating a nuclear explosion over North Carolina. A pair of Mark 29 hydrogen bombs — each of which was 250 times more powerful than the bomb that leveled Hiroshima — were accidentally deployed when the B-52 hauling them went into an uncontrolled spin. One of them fell to the ground unarmed, but the failsafe mechanisms in the other underwent a cascade of failure. Had the bomb exploded, the lethal fallout would have spread across the Eastern Seaboard, blanketing New York and Washington D.C.”
