Today in 1919, a molasses storage tank in Boston's North End ruptured sending a 30' wave of molasses through the streets. It killed 21 people.
I have done presentations on this accident with respect to Project Management issues and comparing issues then with similar issues today. It's an ongoing joke in construction that "You can get it fast, good or cheap. Pick any two". They opted to go for fast and cheap as they had to have it completed in time to receive a shipment of molasses that was then on the way. Short cuts were made. The tank was never filled with water to test for leaks and it leaked so badly that children in the area would get raw molasses of its side. The company painted it brown to hide the molasses stains. It was the worst industrial accident of its day and resulted in urban legends that exist up to today.
