It seems to me we are both over our heads a bit. I hope no one will really take my advice on how to build a rocket ship.

The other thing that is happening is that the discussion is branching out a few different ways. We all know that air resistance becomes a sizable force the faster you go and actually becomes significant to the the complex analysis at speeds greater than 30 or 40 mph. While I on the other hand am just trying to examine the pure physics of mass, velocity, force, power and energy and torque multiplication. For which a rocket in space that doesn't use fuel ( ie lose mass, or gain mass due to relativity or is not flying toward or directly away from a black hole.) is a good example for some things I want to look at up to the point where we talk about torque multiplication and power which rocket scientists don't often car about.
