Can the rocket get off the pad at 1/2 thrust?  If it could get 4-5m away, it
probably could work.

SS... To Orbit.
I mean... landing.  Does one flip when landing on the moon?

I am with you on this.

Given some mcguffin drive that could get us to another star in some
reasonable time, when we arrive, we'll still need to live in a space colony
for a few dozen years before said planet can be made habitable.
(Even if it was perfect, we still need to clear some land and grow some
crops, and find/build local source of power...)
