Folks - this is NOTHING like what SpaceX has accomplished. This vehicle is one stage only, not a booster. It did not leave the atmosphere. It did not go supersonic. It did not deal with re-entry heating. And much more.
While VERY cool, and an amazing accomplishment for it’s time - this is in no way comparable to what SpaceX has accomplished.
