The W-47 warhead had a far more serious problem: I learned about the unreliability of the W-47 warhead during my interviews with Bob Peurifoy and Bill Stevens. Some of the details can be found in Hansen, Swords of Armageddon, Volume VI, pp. 433–41. Hansen called the W-47, without its safing tape, “an explosion in search of an accident.” Sybil Francis touched on the subject briefly in “Warhead Politics: Livermore and the Competitive System of Nuclear Weapons Design,” thesis (Ph.D.), Massachusetts Institute of Technology, Department of Politic Science, 1995, pp. 152–53.
“almost zero confidence that the warhead would work”: Quoted in Francis, “Warhead Politics,” p. 153.

a B-52 on a Chrome Dome mission: The Palomares accident was the most widely publicized Broken Arrow of the Cold War. In addition to weeks of coverage in newspapers and magazines, the event inspired a fine book by Flora Lewis, a well-known foreign correspondent, One of Our H-Bombs Is Missing (New York: McGraw-Hill, 1967). Randall C. Maydew, one of the Sandia engineers who helped to find the weapon, later wrote about the search in America’s Lost H-Bomb! Palomares, Spain, 1966 (Manhattan, KS: Sunflower University Press, 1977). Barbara Moran made good use of documents obtained through the Freedom of Information Act in writing The Day We Lost the H-Bomb: Cold War, Hot Nukes, and the Worst Nuclear Weapons Disaster in History (New York: Ballantine Books, 2009). I relied on those works, as well as on a thorough description of the accident’s aftermath—“Palomares Summary Report,” Field Command, Defense Nuclear Agency, Kirtland Air Force Base, January 15, 1975—and other published sources.
