[Norden] said, with the Mark 15 Norden bombsight, he could drop a bomb into a pickle barrel at 20,000 feet.

Gladwell is invoking the famous marketing claim attached to the Norden bombsight—an emblem of WWII-era faith in “precision” technology. The line highlights how a compelling technical promise (“pickle barrel” accuracy from high altitude) can shape institutional strategy and public belief, even when real-world conditions (weather, flak, pilot stress, mechanical limits, intelligence errors) make such precision unlikely. In Gladwell’s hands, the boast functions as a cautionary example about overconfidence in measurement and engineering, and about how narratives of near-perfect accuracy can justify large-scale decisions with profound moral and human consequences.
