Seiji Yoshihara in the cockpit of his Saro A.17 Cutty Sark, the only example built with a single engine, in San Francisco Bay. It appears that Yoshihara intended to fly this aircraft solo across the Pacific from the USA to Japan, but it crashed at Oakland. Details are hard to find. In 1930, Yoshihara had flown Junkers A50 Junior D-3 from Berlin to Tokyo and in 1931, he attempted a Pacific crossing in a float-equipped Junior, J-BENB, but crashed it off Hokkaido.
