Likewise, large-scale engineering treats patience as risk management. Chariots for Apollo (NASA SP-4205, 1979) details how the lunar module matured through exhaustive subsystem trials long before a single moon landing. Each review, simulation, and failure analysis added invisible scaffolding to a design that had to endure vacuum, heat, and human error. The result illustrates the maxim’s payoff: deliberate planning converts fragile ambition into operational reliability. [...]
