The Martin M-130 was a commercial flying boat designed and built in 1935 by the Glenn L. Martin Company in Baltimore, Maryland, for Pan American Airways. Three were built: the China Clipper, the Philippine Clipper and the Hawaii Clipper. A fourth flying boat (the M-156) called the Russian Clipper was built for the Soviet Union. It was similar to the M-130 but had a larger wing (giving it greater range) and twin vertical stabilizers.
