The planes crashed at about 4 p.m., sending one of the planes, a Cessna 210, into the San Pablo Bay waters about 1 mile north of Brother Island near the Richmond-San Rafael Bridge, Coast Guard Lt. Jeannie Crump said.
Federal Aviation Administration spokesman Ian Gregor said each aircraft in the collision off the city of Richmond had one person on board.
The other plane, a Hawker Sea Fury TMK 20, continued flying for about an hour before landing in Ione, Calif., according to Crump. According to Gregor, the pilot of the Hawker was uninjured.
As of 5:30 p.m. the Coast Guard was searching the waters with four boats and a helicopter. Boats from five other local agencies had also responded, as well as two other agencies’ helicopters. It wasn’t immediately known if the pilot of the Cessna survived.
“We’ve seen lots of debris but no persons yet,” Crump said.
