When a small plane crashed in a California neighborhood, killing two and injuring at least two others, residents raced to save their neighbors from the intense fire and explosions.

       The twin-engine Cessna C340 crashed at 12:14 p.m. local time Monday in Santee, near San Diego, the Federal Aviation Administration said. The plane first struck a UPS truck and then skidded into two homes, destroying them.

       "It was like a bomb went off," witness Andrew Pelloth told ABC News.
