Plane Crash Kills Two Pilots Off Northern California Coast

A small plane en route to Hawaii crashed into the Pacific Ocean shortly after takeoff, killing the pilot and copilot.
The plane was owned by an investment firm of Google co-founder Sergey Brin.
Investigators are looking into fuel issues as a possible cause of the crash.
The plane was equipped with extra fuel tanks but may have been unable to transfer fuel into the main tanks.
The crash occurred about 40 miles off the coast of Half Moon Bay, and the victims' remains were left at sea.
