It was supposed to be the crown jewel of San Diego’s summer. Thousands of people lined the Embarcadero, coolers packed, kids on shoulders, and cameras ready to capture the West Coast's most ambitious pyrotechnic display. Then, at exactly 9:00 PM, the Big Bay Boom 2012 didn't just start. It ended.
In a single, deafening roar, nearly 7,000 fireworks shells ignited simultaneously. The planned 18-minute choreographed masterpiece turned into a massive, blinding white fireball that hung over the water for about 15 seconds. If you blinked, you missed the entire Fourth of July.
Honestly, it’s one of those "you had to be there" moments that felt like a glitch in the matrix.
The Night the Sky Exploded All at Once
San Diego’s Big Bay Boom is usually a model of logistical precision. It uses four different barges stationed throughout the bay—Shelter Island, Harbor Island, the Embarcadero, and the North Embarcadero—all synced via radio frequency to a musical soundtrack. On July 4, 2012, the expectation was a rhythmic, escalating dance of color.
Instead, the barges looked like they were hosting a mini-supernova.
The sound was the first clue that something was wrong. Usually, a fireworks show starts with a few "pioneer" shells—single pops to test the wind and wake up the crowd. This sounded like a jet engine exploding on the water. People in Coronado reported feeling the shockwaves in their chests.
The visual was even weirder. Because every single shell—from the small 2-inchers to the massive 10-inch finales—went off at once, the colors didn't have room to breathe. They bled into a searing, overexposed white light. It was so bright it washed out the night sky, turning the bay into daylight for a quarter of a minute.
Then, total silence.

The smoke was thick, acrid, and hung low over the water like a heavy fog. For the next ten minutes, the crowd sat in confused anticipation. Was this just a really intense intro? Was the "real" show about to start? Local news stations, including Fox 5 San Diego, struggled to figure out what to tell their viewers. The "Boom" had happened, but the "Big Bay" part felt a little empty.
Garden State Fireworks and the "Signal" Error
You’ve got to feel for Garden State Fireworks. They are a legendary family-owned business with a stellar reputation. They had been running the Big Bay Boom for years without a hitch.
So, what went sideways?
The post-mortem revealed a technical nightmare. It wasn't a human pressing the wrong button or a lit match dropped in the wrong place. It was a corruption in the digital firing script. Essentially, a computer file sent a "fire all" command instead of following the chronological sequence.
Specifically, the glitch occurred within the primary control system's "step" command. Fireworks shows of this scale are run by software like ShowSim or similar proprietary firing systems. The barges are linked by a master controller. When the clock struck 9:00 PM, a stray bit of code or a data corruption caused the system to interpret the entire 18-minute script as a single event.
Why the backup didn't save the day
People often ask why they didn't just stop it. You can't. Once those electronic matches (e-matches) receive the voltage, the chemical reaction is instantaneous. You're dealing with gunpowder and magnesium. There is no "undo" button for a thousand shells in mid-air.
Garden State Fireworks was devastated. To their credit, they didn't hide. They took full responsibility. They even offered to do a future show for free to make up for the 2012 disaster. It was a masterclass in PR recovery for a situation that could have easily sunk a smaller company.

The Social Media Birth of a Viral Fail
Back in 2012, Twitter (now X) and YouTube were already huge, but this was one of the first times a local event became a global viral sensation in under an hour.
Within minutes of the "explosion," videos started hitting the web. The most famous one, filmed from a distance, shows the sky turning into a white dome of fire followed by a collective "What was that?" from the crowd.
- The disappointment was real. Families had spent 8 hours claiming spots.
- The humor was instant. Memes about San Diego's "efficient" fireworks show flooded the internet.
- The confusion was localized. Some people on the outskirts of the bay thought a literal bomb had gone off.
Interestingly, the Big Bay Boom 2012 actually helped the event's long-term visibility. While it was a failure in the moment, it put San Diego’s show on the map for people who had never heard of it. Bad press is still press, and the following year, the crowds were even bigger, mostly because everyone wanted to see if it would happen again.
Lessons in Pyrotechnic Redundancy
After the 2012 incident, the industry changed how it handled "all-call" commands. Software developers for firing systems implemented more "dead-man switches" and better file verification protocols to ensure a single corrupted line of code couldn't trigger a mass ignition.
They also started separating the firing scripts into smaller "packets." Instead of one massive file that controls the whole show, modern displays often use modular scripts. If one module fails, the rest of the show can potentially be salvaged.
How to Handle Future Big Bay Booms
If you're planning on heading to San Diego for the Fourth, there are a few things to keep in mind to avoid the disappointment of 2012, even though the show has been flawless ever since.
- Pick the right barge. While all four barges fire the same show, the Embarcadero and Harbor Island usually offer the best acoustic experience because the sound bounces off the city skyline.
- Arrive way earlier than you think. If 2012 taught us anything, it's that the crowd size doesn't care if the show is 15 seconds or 18 minutes. Parking is a nightmare by 2 PM.
- Bring a radio. The music is half the experience. Tuning into 101.5 KGB or 100.7 Big FM (the usual partners) gives you the "story" of the fireworks. In 2012, the music kept playing long after the smoke cleared, which made the whole thing even more surreal.
What to do if things go wrong again
Look, technology fails. If you find yourself at a fireworks show that ends prematurely, don't leave immediately. Most of the time, the pyrotechnicians are frantically trying to reboot the system. In 2012, there was nothing left to fire, but in many other "fail" scenarios, the show resumes after a ten-minute delay.

Moving Past the Fireball
The Big Bay Boom 2012 remains a legendary piece of San Diego lore. It’s the kind of story locals tell newcomers every July. It’s a reminder that even with the best technology and the most experienced experts, nature (and code) can be unpredictable.
The event organizers, the Port of San Diego, and Garden State Fireworks eventually turned the disaster into a victory. The 2013 show was billed as a "comeback," and it delivered. It was longer, louder, and—most importantly—it lasted more than 15 seconds.
If you're a fireworks enthusiast, 2012 isn't a reason to stay away. It’s a reason to appreciate the incredible amount of work that goes into making sure thousands of explosions happen exactly when they’re supposed to.
To dive deeper into the logistics of the event or to see the current year's schedule, you should check the official Port of San Diego website or the Big Bay Boom’s dedicated portal. They usually release the barge locations and public transport maps by late May.
For those looking to photograph future shows, remember:
- Use a tripod.
- Set your shutter speed to "Bulb" mode.
- Keep your ISO low (around 100 or 200).
- And maybe, just in case, keep your finger on the shutter the moment 9:00 PM hits. You never know when you might catch another 15-second supernova.
