Wow, reminds me of the old ‘50s movies, “Rocket ship XM” and “Destination Moon”. They showed the rockets landing on their tail using the rocket motors to land gently. If this is the first stage it shouldn’t have to go all the way into orbit, depending on how they have it set up.
If for any reason you can’t view the video it’s also on this page:
