In fact, a hydrogen bomb had been mistakenly released over Albuquerque the previous year. Knocked off balance by air turbulence while standing in the bomb bay of a B-36, the plane’s navigator had steadied himself by grabbing the nearest handle—the manual bomb release. The weapon broke through the bomb doors, and the navigator held on to the handle for dear life. The H-bomb landed in an unpopulated area, about one third of a mile from Sandia. The high explosives detonated but did not produce a nuclear yield. The weapon lacked a core.
