Dream of Japanese aircraft designers during the ww2.
Kunitake Kiyohara (1910- ), Chief-designer of the Kyusyu J7W Shinden, describes it in an alumni magazine of Nana-ko high school (present Kagoshima university) like this.
"I was looking forward to the plane flying with the turbine rocket engine (present turbo jet engine) as J7W2 but it was not in time for the war. I had no more chance to do with it but am really glad to see many rockets are being launched from our land Kagoshima today."
