&gt;&gt; I imagine is something you would have to design a larger rocket around, rather than add in after the fact.<p>Control authority.  That is the measure of margin a system has over a feedback mechanism&#x27;s (in case of a rocket: ability to accurately apply thrust in correct vector at required frequency) ability to dampen uncontrolled perturbations.<p>I&#x27;d bet you that SpaceX has just as thoroughly understood and tested their working margins on their landibg system&#x27;s control authority as has Blue Origin.  For this reason I don&#x27;t believe Blue Origin has any technical advantage over SpaceX in the manner you imply they do.<p>This might be hubris, but there aren&#x27;t too many things us humans don&#x27;t understand about rocket design at this point. The last big one was the waterhammer effect in turbo pumps supplying rocket fuel.<p>Understanding 1st, 2nd, and 3rd harmonic vibrations in mechanical systems is standard practice in rocket and any other airframe design (Boeing airframes, missiles&#x2F;rockets, etc). It&#x27;s a solved problem.<p>If Bezos is hanging his hat on this argument, he&#x27;s reached the limit of his omnipotence.
