Police said about six juveniles were fighting in the back of the bus. When the driver stopped, one of them left through the back door and then fired into the bus.

Underground cables overheated and caught fire, causing a manhole cover to explode, cutting power for two blocks.

Killed in the crash were the pilot, 67-year-old Monroe Smith of Glenside, Pennsylvania, and a photographer, 45-year-old Christopher Dougherty of Oreland, Pennsylvania.
