Before Power 2.0 dropped, Reactor FTL Chambers were simply known as jump drives. However, The name Reactor FTL (faster than light) Chamber is actually incorrect using default settings. Assuming that it takes 1 second to jump between 2 arbitrary points, the distance not exceeding 8 sectors (16 km, 9.94 miles) you only then travel 9.94 miles per second, nowhere close to the speed of light. So while the name sounds cool, it is incorrect. Could it please be fixed in the next patch?
