The WrestleMania 24 pyro incident
>Fireworks were being set off all over the Camping World Stadium in Orlando, Florida. There were cables the fireworks were sliding down, and successfully too for the first few times — until around the fourth go around. The fireworks slid down a rope that suddenly snapped and landed into a mass of people in the crowd. There were about forty people injured, receiving burns and welts. Although most of the injuries were thankfully minor, three people left in an ambulance and were treated in a hospital.https://youtube.com/watch?v=_vbJLKWxVZE&feature=share8
