The Aichi M6A1 Seiran ("Clear Sky Storm" or "Mist on a Fair Day") was a submarine-launched attack floatplane designed for the Imperial Japanese Navy during World War II. It was intended to operate from I-400 class submarines whose original mission was to conduct stealth aerial attacks against the United States. (Be carful pitching the plane to high or low too quickly to avoid flipping, use the VTOL slider if you have trouble taking off, when taking off from the water keep the left stick down from the begining until you take off, water landings must be done gingerly) check out the real thing here http://www.brook ksart.com/Seiran.html
