RIO VISTA, Calif. (AP) — Officials say a small plane and a helicopter have collided in the San Francisco Bay Area. It's not yet clear if anyone was injured.
Federal Aviation Administration spokesman Ian Gregor says the six-seat Beechcraft Bonanza and the two-seat Robinson R22 helicopter collided Sunday near the small Rio Vista Municipal Airport 50 miles northeast of Oakland.
Gregor says the helicopter went down about eight miles south of the airport, and the plane was attempting to land at Byron Airport about 20 miles farther south. It's not clear yet whether the plane was able to land.
Gregor didn't yet know how many people were aboard each aircraft, or if anyone was hurt.
The FAA and the National Transportation Safety Board will investigate. Sacramento television station KCRA reports the NTSB typically posts a preliminary report within a week or two of the accident, but can often take months to determine a probable cause.
