There seems to have been a big boom. And then it was over. While most fireworks displays across the country featured a steady stream of pyrotechnics over the course of about fifteen minutes, viewers in San Diego Bay were treated to a 15 second show where all the fireworks apparently exploded at once.

If you secretly wanted to see what happens when fireworks launch this quickly, this is what it looks like. It’s called “premature ignition,” as the Coast Guard described it to the U-T San Diego. And it seems there was a spectacular explosion to kick the night off, even if things ended pretty quickly.

A statement posted by the Big Boom website for the Port of San Diego described the “premature ignition” as due to an unidentified technical problem. In one clip posted on YouTube, right during the middle of the rapid fire launch of the fireworks, an off camera viewer muses, “That was a good start to that, you don’t often see the grand finale at the beginning.”
