A single-engine plane with four people aboard crashed into a Clairemont home and burst into flames Saturday, killing two passengers and destroying the house, authorities said. The accident occurred about 4:35 p.m. when the Beech B36 Bonanza crash-landed in the baseball field of Lafayette Elementary School and skidded into the back of a home on Chandler Drive near Mt. Abernathy Place. Neighbors said a family with a baby are renting the house. They were not home at the time. Their two dogs perished inside the house, neighbors and authorities said.
