DAYTON, Ohio (AP) _ A plane performing a stunt crashed into a runway Saturday before thousands of people at an air show, killing the pilot, an official said.

The plane was one of two making loop-to-loops with smoke trailing as part of the annual air show at Dayton International Airport. It slammed into the runway across a field from spectators and caught fire.

The crowd stood stunned as the show was shut down, witnesses said.

The pilot was taken to Miami Valley Hospital and pronounced dead, said Cheryl Page, a nursing supervisor.

Fire trucks sprayed foam on the wreckage to extinguish the fire.

No other details were immediately available, said Brenda Kerfoot, the show's general manager.
