A massive fusillade of bright rocketry lit up North Island and the downtown area just before 9 p.m.. YouTube video from the scene showed a gigantic 28-second blast, with rockets and bombs bursting in a random pattern. Then, nothing.

“It looked like a planet coming,” one spectator said. A civilian dispatcher at the San Diego Coast Guard station said “it looked like the finale … you know, right at the end they shoot off everything.

“It took 25 minutes to get the word out” that the entire fireworks show had blown at once, said the controller, Rich Dann.

More than 500,000 people were expected to line the bay for the big blast.
