SAN FRANCISCO, April 29 (UPI) -- The two vintage planes that collided over San Francisco Bay, bringing one of them down, may have been flying in formation with a third plane, investigators say.
The three aircraft were returning from the Pacific Coast Dream Machines show Sunday in Half Moon Bay south of San Francisco. Jimmy Lee, a spokesman for the Contra Costa County Sheriff's Office, said the wreckage of the crashed plane, a 1965 Cessna 210, was found Monday.
