And it was vectored down through the floor at the center of mass somewhere in the big orange tank, which is why the shuttle always did a sick Tokyo drift off the pad.
Thrust from rocket engines(or jet engines) is not lift. The force they genarate is perpindicular to the focre genarated by lift. All of the lift being genarated in front of the CG would cause the rocket to pich over and crash back into the ground.
The amount of lift made has a lot to do with the angle of attack, the angle between the relative wind and the mean chord of the wing. While the space shuttle is in gliding flight, it flew with a very nose high attitude in a reasonably steep descent, thus the angle of attack. Under rocket power on ascent, the relative wind would be coming pretty much nose on, so a very low angle of attack, thus very little lift.
If the angle of attack goes negative, the wing will lift in the other direction, which is how planes can fly upside down.
Yes but it would still generate lift - a force witch would not be aligned with the center of mass and while not massive would be enough to pitch over the rocket and destroy it. There is a reason the x37 flies in a payload faring.
I’m going to bet that we won’t see another spacecraft of the same plan as the shuttle. We barely got it to work, the Soviets managed a single unmanned test flight of something similar, and we’ve got vertically landing reusable rockets now. Large space planes I think are a dead end.
The only way I can see another “space-plane” design is if we actually get skyhooks working. As long as we are using rockets it doesn’t make sense. Sure it was cool AF when we were kids, but yeah, the design is just a safety nightmare
It is my understanding that at least one small, unmanned space plane is in use by the US military. Something small enough to fit in the payload fairing of a commercial or military rocket that can be put in space, flown for a little while then landed at an air force base probably serves some function.
But I’m convinced large space planes on the order of the space shuttle are now museum pieces and/or debris.
When basically all of your “lift” is coming from thrust, sure it does. As if the space shuttle stack was a work of aerodynamic genius.
Like 30% of the shuttles launch thrust came from the main engines.

Aerodynamic lift has a lot to do with angle of attack. Source: I am a flight instructor.
Wings still genarate lift when in a vertical climb. The force genarated is reative to the wings not gravity

But but, it could glide*!
*Kinda, and the parachutes are slower. It also has to piggyback on a 747 to be moved anywhere.
