Charting the incredible strides the Japanese aircraft designers made during the 1930's and their subsequent ground breaking developments during WWII. These culminated in the development of helicopters, rocket fighters and long range aircraft designed to strike at the US West coast armed with biological weapons. In the 1930s, Japanese designers created a range of warplanes, culminating in the legendary Ki-43 "Oscar" and the A6M "Zero". As the war turned against Japan, designers created the rocket-powered "Shusui", the "Kikka" jet fighter, and the experimental R2Y"Keiun". We also disclose frantic preparations to assemble a secret airforce of jet and rocket planes to counter an anticipated U.S. invasion in1945, and chronicle post-war aviation and the birth of the Japanese rocket program in the 1950s and '60s.
