"A ship’s Acceleration is five times the Speed rating. This is measured in miles-per-turn (which, if you care, means that a ship with Speed five moves at about twenty-five miles per turn or eight miles per second, and the speed of light is about fifty miles per second)."

​this is wrong. speed of light is almost 200k miles per second. page 8, bottom left paragraph

if this book gets redone. I hope they fix this mistake
