The Sikorsky S-43 was an eighteen place twin engine amphibious aircraft.
It was known as the "Baby Clipper" (Army OA-1, USN JRS-1) in airline service. It was used primarily by Pan American World Airways for flights to Cuba, but three were also used by Inter-Island Airways of Hawaii, the predecessor to modern-day Hawaiian Airlines, to ferry Pan-Am Clipper passengers and local residents from Honolulu to the other islands.
