Yeah, they mentioned Koro Sensei wasn't fast enough to break the atmosphere like Anthony said, his max speed is Mach 20 and if I remember clearly they said was a little bit more than was possible. Mach 1 is the speed of sound Mach 20 is 20 times the speed of sound so it's not a matter of small amount of speed. I mean mach 1 is generally considered 761mph, so it would take being able to move a few thousand miles per hour faster.
