Hood's destruction came from an extreme convergence of timing, trajectory, and vulnerability. The decisive shot would have been extraordinarily difficult to reproduce. That spectacular loss helped create the idea that battlecruisers universally had a glass jaw. The conclusion is too broad because hits elsewhere on Hood could have been absorbed without producing the same catastrophe.
