Just after 9 a.m. on Aug. 29, a group of U.S. airmen entered a sod-covered bunker on North Dakota’s Minot Air Force Base with orders to collect a set of unarmed cruise missiles bound for a weapons graveyard. They quickly pulled out a dozen cylinders, all of which appeared identical from a cursory glance, and hauled them along Bomber Boulevard to a waiting B-52 bomber.
The airmen attached the gray missiles to the plane’s wings, six on each side. After eyeballing the missiles on the right side, a flight officer signed a manifest that listed a dozen unarmed AGM-129 missiles. The officer did not notice that the six on the left contained nuclear warheads, each with the destructive power of up to 10 Hiroshima bombs.
That detail would escape notice for an astounding 36 hours, during which the missiles were flown across the country to a Louisiana air base that had no idea nuclear warheads were coming. It was the first known flight by a nuclear-armed bomber over U.S. airspace, without special high-level authorization, in nearly 40 years.
The episode, serious enough to trigger a rare “Bent Spear” nuclear incident report that raced through the chain of command to Defense Secretary Robert M.
