&gt;Also, note that delta-V is not thrust. Delta-V is a change in velocity, thrust is force.)<p>Thanks for the condescending reply. Seeing as I have a degree in Physics, I am well aware of the technical difference between thrust and delta-v. However, when talking about rocketry, it&#x27;s hard to have delta-v without corresponding thrust, and my usage of both terms was more for rhetoric than a desire for absolute technical correctness.
