Actually, the Tacoma Narrows Bridge disaster...was the engineers fault.


Tacoma Narrows Bridge collapse - Failure magazine

While it’s unclear whether the Narrows’ principal engineer, Leon Moisseiff, was aware of the problems plaguing these other new bridges (he almost certainly was), he argued for cost-cutting adjustments to the original design and against initiatives that would detract from the bridge’s appearance.

Meanwhile, an advisory engineer named Theodore Condron strongly and repeatedly urged that the Tacoma Narrows be built at least 25% wider. Condron, a lone dissenter, was ignored, though his fears quickly proved justified as the bridge began behaving abnormally even during the construction process.
