6. Texas City Disaster
One of the biggest disasters in the history of USA occurred on April 16, 1947, when a fire broke out on a ship taking about 600 lives. The ship was carrying bags of ammonium nitrate and when the fire broke out and killed all those people, another ship that was nearby exploded sixteen hours later, and even two planes flying at 1500 feet were knocked off. This caused a wave more than 15 high which destroyed the areas nearby. This domino-effect tragedy might have been prevented because it is believed that a cigarette could be the cause of it.
