Folks in San Diego witnessed what was either the worst Fourth of July fireworks celebration — or the absolute best — when a technical malfunction caused all of their pyrotechnics to go off at the same time. The annual Big Bay Boom extravaganza began and ended in spectacular fashion when an inadvertent signal set off the explosions about five minutes early and caused the entire 18 minute show to take place in about 15 seconds. Confused spectators waited around for what they thought was going to be the rest of the show, but were sent home and told the show (that was supposed to be choreographed to music) was canceled.
