[00:00:00]August 29th, 1907.

[00:00:02]75 workers stood on the Quebec Bridge as it neared completion. In 15 seconds, they were all dead. The massive steel structure didn't just fall, it pancaked into the St. Lawrence River like a house of cards. Workers who survived the initial collapse were trapped in twisted metal below the water. Their screams echoed across the river as the bridge folded like paper beneath them.

[00:00:25]Engineers had ignored critical warning signs for months. They knew the bridge was failing, but construction continued anyway.
