The Mitsubishi J8M "Shūsui" (Japanese: 三菱 J8M 秋水, literally "Autumn Water", used as a poetic term meaning "Sharp Sword" deriving from the swishing sound of a sword) was a Japanese World War II rocket-powered interceptor aircraft closely based on the German Messerschmitt Me 163 "Komet". Using only the above description and what you know about the world, "Autumn Water is a poetic term that means the same thing as the name that came from the sound of a swishing sword." is definitely correct, incorrect, or inconclusive?
