The New London School Explosion took place in 1937 in New London, Texas, as the result of an undetected natural gas leak. The gas accumulated in a crawl space under the school and filtered through the building until it made contact with an electrical source, igniting an explosion that collapsed the structure. Estimated fatalities range from 296-319, making it the worst school disaster in U.S. history. Natural gas is difficult to detect because it is invisible and odorless, but, had the leak been discovered soon after it began, the explosion could have been prevented. For this reason, Texas mandated adding mercaptans to natural gas to make it odorous, and make leaks detectable. This soon became standard practice worldwide. http://www.youtube.com/watch?v=aKt01p3DJRw
