Two veteran California pilots were killed over the weekend when their World War II-era planes collided in midair while preparing to land just after finishing first and second in a title race at the National Championship Air Races north of Reno. Officials identified the victims of Sunday's crash as Chris Rushing of Thousand Oaks and Nick Macy, 67, of Tulelake. Race officials said they were cooperating with the National Transportation Safety Board, the Federal Aviation Administration and local authorities to determine the cause of the crash.
