Two private planes flying about a mile from an airport collided Sunday, killing five people and raining debris down on car dealerships below, US authorities said. Two people were killed from each plane, and the fifth was inside a Chevy dealership that was hit by wreckage, said Wayne Pollack of the National Transportation Safety Board. The small Cessnas collided Sunday afternoon near the small Corona Municipal airport and a freeway in Riverside County, about 45 miles (70 kilometers) southeast of Los Angeles, Federal Aviation Administration spokesman Allen Kenitzer said. Kenitzer did not immediately know where either plane was headed or whether there were any distress calls. The Corona airport does not have a staffed control tower, he said.
