ST. AUGUSTINE, Fla. -- The sighting of two fiery balls flying across the sky in St. Augustine is causing quite a stir.

The Puckett family said they spotted what they believe was a UFO on Saturday night. A man in Germany also claimed to have seen the same fiery balls.

Some, though, say the explanation is that they are life-sized hot air balloons called "sky lanterns," traditionally used in Asian festivals.

The lanterns can rise nearly 5,000 feet and travel for miles.
