"Five thousand times the speed of sound? How is that even possible?" The chief engineer's face practically had "impossible" written all over it.
Five thousand times the speed of sound was almost equivalent to one-twentieth the speed of light. Not to mention whether the engine technology could reach such a level, or if it could even have such powerful thrust.
But just the immense load from that instantaneous acceleration was something no material and no person could withstand. Even if calculated using the manned rocket's first cosmic velocity, the massive acceleration's pressure could make even a professionally trained astronaut spit blood.
Reaching five thousand times the speed of sound instantly, no doubt, even a Divine-level Superpower User couldn't withstand it. The heat generated from such acceleration and air friction could easily melt any metal on Earth, even theoretically, it's impossible!
