What types of propulsion do you think of when you hear the word "plane"? Jets? Propellers? Maybe VTOL engines with their variable nozzles? There is one more... Missiles! Yes, literal missiles! This design uses 2 cleaver-powered 'Kunai' engines, (trust me, it's totally safe to mount 2 50-kiloton missiles on an airplane!). This comes with several advantages! First, since they don't count as engines, it opens up lots of cheating opportunities! No engines allowed? No Jets allowed? No problem! Another advantage is a nearly instantaneous accelaration, I mean, it is a heckin' rocket engine after all. The only real problem is that the 'Kunai' engines are very big and bulky and don't provide much of a top speed. But who knows! Maybe you know a solution to those problems! Feel free to use this idea yourself!
