San Diego fireworks fiasco blamed on overzealous computer backup Just one week after the San Diego Big Boom fireworks fiasco -- when an elaborate Fourth of July fireworks display was spectacularly ruined after all 7,000 fireworks went off at the same time -- we finally know what went wrong. The trouble? Well, it's complicated. The explanation from Garden State Fireworks, the company responsible for the mishap, is so convoluted no one seems to be sure exactly what happened. It had something to do with an overzealous backup computer file that overlapped with the primary file to accidentally set off all the fireworks at once. "Contrary to numerous opinions and theories, the simultaneous ignition was not due to any sabotage or massive computer hardware failure," Garden State Fireworks wrote in a lengthy statement that may require a PhD in firework-ology to fully understand. The display sequence started exactly when it was expected to and the systems executed the file the way it appeared. Sadly, the file executed was the double file created in the back-up plan download process. The statement goes on to say that the company is "heartbroken" that the estimated 500,000 people who showed up to watch the show did not get to see the fireworks go off as planned, but also that it is confident its technicians did everything they could to ensure the show would go off as expected. "Everyone's seen their computers crash, everyone's seen their cell phones drop calls," August Santore, Garden State's owner, told NJ.com. The only way to correct anything that's not working properly, you have to live it. In this particular case, it's something that was unknown. It's never happened. But now that it has happened, the company said it will take steps to make sure it never happens again. Garden State Fireworks also noted that the San Diego Big Boom fireworks display is one of the most logistically complex displays in the world because it spans 14 miles and has five locations involved in the show. While the fireworks display may have disappointed its intended audience, it seems to have delighted an entirely different audience on YouTube. As of last week, videos of the fireworks going off all at once had been viewed more than 4 million times.
