God I'm such an idiot, I always thought gravity pulled rockets downwards and you need to apply thrust to take off, but it's the other way around! You run the engines to stay on the ground and board the rocket, then just switch them off to start!

And the recursive raptor engine that contains itself three times, genius!

Well, you see the gravity thing only works for the lower third of the rocket. Then gravity changes direction, that's why you need the engines to create thrust

Well it helps when aerodynamic drag pulls you upwards. I thought it was a drag force, but I guess it's a bit of a misnomer.
