Plane crash in Concord kills 1

CONCORD, Calif. - A plane crashed Monday in Concord, killing the single pilot flying the Cessna 152, officials said.

The plane had taken off from the airport about a hour before the fatal crash on federal land near Buchanan Field Airport, according to the Federal Aviation Administration. 

On Tuesday, the Contra Costa County Coroner identified the pilot as Christopher Rampoldt, 69, of Martinez.

It remains unclear what happened between the 10:30 a.m. take-off and the 11:30 a.m. crash.

Contra Costa County Fire Protection District Marshal Robert Marshall said federal firefighters at the military base responded to the crash.

The FAA and National Transportation Safety Board will investigate the plane crash, said FAA spokesman Ian Gregor.
