Company investigating what caused all of the fireworks to go off at once

SAN DIEGO (AP) -- The company that produced Wednesday night's fireworks show in San Diego says it's trying to find out why the tens of thousands of fireworks that had been set up on four barges and a pier all went off at once.

August Santore, a part-owner of the company, says a glitch or virus in the computer firing system caused all of the fireworks to go off with one command, minutes before the show had been scheduled to start.

He says the precautions that were in place helped keep anyone from being injured.

Santore says the company feels "terrible" about the mishap, which was witnessed by hundreds of thousands of people. The company produced hundreds of holiday shows across the country last night.

Online video shows multiple explosions in the shape of light bulbs flaring up from barges in the bay. They began to fizzle and sputter in a matter of seconds.

One spectator told U-T San Diego that people in the crowd figured there must have been some budget cuts.

The 12th annual Big Bay Boom show was supposed to last 20 minutes. Nobody was hurt when the fireworks mis-fired.
