Completely amazing! I&#x27;m sure I heard a &quot;holy shit&quot; or two there in the audience. :)<p>EDIT: One question for the rocket scientists here: exactly <i>how</i> reusable do they expect these returned first stage rockets to be? What is the process of certifying that a returned rocket is fit to fly, and what components are most likely to need repairing&#x2F;replacing with each launch?
