SAN JOSE - A sea of foam has spilled out of a hangar at Mineta San Jose International Airport in California and onto an adjacent street.

San Jose Fire Capt. Mitch Matlow tells The Mercury News the foam is a chemical used as a fire supression agent and is coming from the hangar's fire prevention system. Matlow says the agent discharged accidentally.

By Friday afternoon, the foam had surrounded two tanker trucks and spilled onto the street. Crews were on the scene.
