Authorities say two pilots were taken to hospitals with minor injuries after a small plane clipped a helicopter in the air over Northern California.

Law enforcement and Federal Aviation administration officials
say the six-seat Beechcraft Bonanza plane clipped the two-seat
Robinson R22 helicopter at about 7 p.m. Sunday. It happened near
the small Rio Vista Municipal Airport halfway between Oakland and
Sacramento.

No specifics on how the crash happened were immediately
released.

Federal Aviation Administration spokesman Ian Gregor says the
helicopter landed in a field about eight miles south of the
airport, and the plane landed short of the Byron Airport about 20
miles to the south.

It's not clear if there were any other people aboard the two
aircraft.

The FAA and the National Transportation Safety Board will
investigate.
