At 3:10 PM on May 31, 1889, Johnstown, Pennsylvania, seemed perfectly normal. Children laughed, factories hummed, and people finished lunch… Until a neglected dam failed—and a wall of water taller than buildings destroyed an entire town in minutes. Over 2,200 lives were lost—more than the Titanic. Most victims were never identified. No warning. No justice. This disaster was preventable, but history barely remembers it… until now. 🔥 If this shocked you, like, comment, and follow for more unbelievable historical stories you won’t learn in school.
