Japanese aviator Baron Kiyotake Shigeno in the Wakadori-go, an aircraft of his own design built by Charles Roux, in flight at Issy-les-Moulineaux in May 1912, a month after its first flight. The aircraft’s 50-60 h.p. Anzani engine was fitted with a Cyrnos wing, although it is unlikely the latter was taken along with the aircraft when it was transported by ship to Japan later that month.
