SAN DIEGO, Cali. — San Diego’s biggest fireworks show fizzled Wednesday in a matter of seconds.

Thousands of spectators were left disappointed in the dark.

Organizers said a “technical glitch” caused all the Fourth of July fireworks to go off at once.

The 12 Annual Big Bay Boom show was supposed to last 20 minutes.

Nobody was hurt when the fireworks misfired.
