Firework display over in a flash

A Californian city's Fourth of July fireworks celebration has gone viral on YouTube - after the whole display went off at once.

Thousands of spectators had gathered in San Diego's Glorietta Bay to enjoy the display, billed as the Big Bay Boom.

But it was all over in 60 seconds when a technical glitch caused all the fireworks to ignite at once.

Rich Dann, a local coastguard, told a local newspaper: "I've never seen so many fireworks go off at one time."
