The Indiana State Fair stage collapse was an incident during an August 13, 2011, outdoor concert by Sugarland as part of their Incredible Machine Tour at the Indiana State Fair in which a wind gust from an approaching severe thunderstorm hit the stage's temporary roof structure, causing it to collapse. The structure landed among a crowd of spectators, killing seven people and injuring 58 others. The members of Sugarland were in a tour bus preparing to come on stage when the collapse occurred at 8:46 p.m. Opening act Sara Bareilles had completed her performance prior to the incident. Events leading up to the collapse Discussions about delaying the show Throughout the day and evening of the concert, the National Weather Service issued notices and warnings predicting strong thunderstorms. Messages about the forecasts were relayed to various State Fair personnel via an automated text-messaging system. At 8:00 p.m., Cindy Hoye, Executive Director for the Indiana State Fair Commission, held a meeting to discuss what effect the weather forecast would have on the 8:45 p.m. start time for the Sugarland show. Members of the meeting were told that the storm was forecast to arrive at 9:15 p.m., 30 minutes after the concert was to begin. Hoye wanted to delay the show until the weather had passed. An official took this message to Sugarland's managers, who said they preferred to go on with the show as scheduled and only stop if weather conditions worsened. The managers only knew about the rain, not the lightning, wind, and hail that were expected. They decided to start the show just 5 minutes late (8:50 p.m.) to allow the band time to warm up. When the band's decision got back to Director Hoye, she accepted, assuming the band had the final say. Since the storm was to arrive at around 9:15 p.m., there would still be time for them to perform some of the show. Evacuation announcement and concert cancellation At around 8:30 p.m., Director Hoye encountered State Police Captain Brad Weaver. Weaver was concerned that the approaching weather would pose a threat to public safety, and recommended that Hoye cancel the show. He also recommended they put together an evacuation plan for the crowd. Hoye directed her staff to make preparations for an evacuation. At 8:39 p.m., the National Weather Service issued a severe thunderstorm warning indicating that hail with a diameter of and winds over
