Earlier this week I went to an entertaining talk by the writer Malcolm Gladwell, author of The Tipping Point, Blink and other bestsellers. Midway through he made a throwaway comment about the bombing of Hiroshima in August 1945. ‘Imagine how it felt to be the pilot who dropped the bomb on Hiroshima – how do we feel about that kind of moral responsibility?’ The implication of this rhetorical question was that the pilot must have been desperately wrestling with the ethical consequences and dilemmas of releasing the world’s first atomic weapon on the unsuspecting city. Malcolm Gladwell is mistaken. In actual fact, the US Air Force pilot, Paul Tibbets, experienced no profound moral quandaries about his actions, either before or after dropping the bomb that killed an estimated 140,000 people. In a revealing interview with the oral historian Studs Terkel in 2002, when aged 87, Tibbets described exactly what happened on the historic mission in the Enola Gay.
