May 21, San Quintin, Mexico / Beech Bonanza

At 09:30 PDT, an instrument rated private pilot and his two passengers were killed when their Beech V35 descended out of control and crashed into water near San Quintin. The airplane was participating in medical relief operations in isolated regions of Mexico. The flight, which was originating at the time of the accident, was destined for Mexicali, where it was due to clear Mexican Customs. The 66-year-old pilot, who had no history of heart disease, reported earlier that morning that he was not feeling well, with symptoms of nausea and an upset stomach. After takeoff, the pilot made a routine radio report about cloud tops. Thereafter, the airplane was observed descending out of a stratus layer of clouds over the bay in a nose down attitude.
