The Ohka was the kind of plane a teenage boy would design if he wanted to make the most badass plane imaginable, but also didn't know anything about planes. And had no regard for human life.
"If we cut out the seat belts we can fit in another 2 lbs. of explosives."
It was powered entirely by not one, not two, but three rockets, and was capable of diving at speeds of over 650 mph, all while equipped with a 2,646-lb. explosive warhead. So it was a huge, piloted cruise missile, in other words. Which sounds awesome, unless you're the guy flying it.
Its wings were made of plywood covered with fabric, it had no ejector seat or landing gear and there was no way to fire the aforementioned giant warhead. The plane's entire method of attack was to dive toward enemies and blow itself to pieces, hopefully destroying its target in the process.
"Wait, what? Where's the landing gear again?"
