According to the LA Times, 28 people were injured in Simi Valley, when their fireworks show went horribly awry.
2 minutes into the show, all the fireworks started going off it once, with many, apparently, going off sideways towards the crowd.
"There was a big boom. Everybody started running down the street. People were screaming,” said Justice Allen, 17, of Simi Valley. "Everybody was just terrified. People hid in bushes."
