HAPPENING NOW L: Big Bay Boom fireworks 🎇 | The Best of San Diego

On July 4, 2012, the "Big Bay Boom" fireworks display in San Diego became a viral sensation when all 7,000 fireworks exploded simultaneously in less than a minute. This massive premature discharge was caused by a computer malfunction due to a corrupted file in the firing program. Although no one was injured, the planned 18-minute show was over almost as soon as it began. Credit: Dan Roy | History In Pictures
