Narrative

DEPARTED RIO DE JANEIRO AT NIGHT. CAPT BECAME ILL DURING CRUISE (3 MAN CREW ON WDB). HE HAD TO LIE DOWN IN BUNK. WE HAD PASSED AREA OF SEVERE WX N OF RIO; EXPECTED HIM TO GET WELL AFTER A FEW MINS; HOWEVER HE STAYED SICK FOR SEVERAL HRS. NOT MUCH IN WAY OF ARPTS. KEPT FLYING N; FIGURED HE'D GET UP. AT THE VERY LEAST WE COULD LAND IN SAN JUAN. DIDN'T WANT TO RETURN TO RIO AND GO THROUGH SEVERE WX; ETC. I AM AN 'OVER 60' X-WDB CAPT; NOW SO. SAT IN L SEAT DURING CRUISE (VERIFIED WAYPOINTS; HELPED WITH RADIOS) AND ALSO SAT AT SO PANEL TO CTL SYS (MOSTLY FUEL; ETC). CHKED ON CAPT NEAR SAN JUAN. HE WAS FEELING BETTER (SOMEWHAT) AND HE GOT UP AND RETURNED TO SEAT TO JFK. FO FLEW AND MADE LNDG. CAPT WAS FINE AFTER PASSING BERMUDA. FLT ATTENDANTS VISITED COCKPIT ON OCCASION AND NOTICED THE SIT. DID NOT SEEM TO UPSET THEM. SUGGESTION: HAVE A RELIEF PLT ON BOARD FOR A 9:30 HR FLT LIKE THIS AT NIGHT. IT WAS (AND STILL IS) MY JUDGEMENT THAT I WAS BETTER ABLE TO HELP IN THE L SEAT; ESPECIALLY IN AN AREA OF POOR COMS; LANGUAGE PROBS; ETC; THAN STAYING ONLY AT THE SO'S PANEL. WE DID NOT KNOW THAT THE CAPT WOULD STAY SICK SO LONG.
