Functionality Mistakes Throughout History That Were Way Too Expensive to Fix

In 1889, Johnstown, Pennsylvania, witnessed a devastating flood due to the South Fork Dam collapse after heavy rain, causing $484 million in damages. Known as the Great Flood of 1889, it’s a historical event that still resonates with Pennsylvanians today.

Over a century passed before the true cause of the Johnstown Flood was revealed. Modifications by the South Fork Fishing & Hunting Club compromised the dam, leading to the death of 2,209 people. Initially, an investigation mistakenly absolved any malpractice.
