One of the largest Fourth of July fireworks shows in the nation came to an abrupt end in San Diego Wednesday after a glitch caused all the pyrotechnics to ignite all at once.
What was supposed to be an 18-minute show ended in seconds, albeit with a extremely intense display of firepower.
The Coast Guard called it a "premature ignition" while event organizers called it "a technical glitch."
In a statement, the port said that just before the fireworks all exploded, technicians had sent a signal "to the barges that would set the timing for the rest of the show after the introduction." But they're not sure what happened.
The Big Bay Boom is advertised as one of the largest fireworks shows in the nation, and boasts about attracting half a million spectators.
People line up for hours and taken advantage of special Fourth of July hotel rates so they can watch the show from their rooms. Needless to say, this year's display is being called the Big Bay Bust.
