On July 4, 2012 in San Diego, California, thousands of people gathered for the ‘Big Bay Boom,’ attending what they thought would be a 17 minute show.
Instead, 7,000 fireworks accidentally went off all at same time.
The fireworks were triggered from a computer however a glitch in the software changed everything.
The 17 minute show lasted just 30 seconds but was remembered as one of the greatest firework shows of all time.
Happy 4th 🇺🇸
