The deadliest nightclub fire in US history, the Cocoanut Grove fire claimed 492 lives. When the fire broke out, the Boston, Massachusetts, club was packed well beyond capacity. About 1,000 people were inside, with limited avenues of escape. Side doors had been locked to prevent patrons from skipping out on tabs, and the main entrance, a revolving door, was rendered useless by the crush of the crowd, as were other unlocked doors that opened inward. What is one theory as to what sparked the fire? Discuss
