74 killed in explosion at Indiana State Fair in 1963

August 14, 2011 (INDIANAPOLIS)

On Halloween night in 1963, 74 people were killed and nearly 400 were injured in an explosion at the fairground's Coliseum.

It was just after 11 p.m. when skaters were finishing a performance. No one realized that propane gas was leaking from a rusty tank in the concession area, slowly filling the unventilated room. The gas came in contact with an electric popcorn machine igniting the deadly blast.
