there are huge forces to balance with high accuracy. I just had a smile thinking of a 2.934,8 tons broomstick (Saturn V start weight) balancing
Indeed, and a few of those who rode the Saturn V commented that in the few seconds after launch the balancing/steering process wasn't at all progressive or gentle. Mike Collins commented that it felt like you were in a car being steered very jerkily, and I think it might have been Bill Anders who commented that it was so bumpy just after liftoff that he thought they must hitting the launch tower.
