Nothing is perfect, but the Shuttle -- 70's technology -- did what
nothing before had done. It regularly put men into orbit with plenty
of cargo capability. It could launch satellites or retrieve them.

What direction is that? Not taking a step backward, I hope. And, not
taking 12 years to do it.

A 6 minute SSME burn with a very high mass ratio and a 'spaceplane'
could make orbit easily. In fact, there would be fuel left over, which
there should be.

He3 fusion has been done at the University of Wisconsin. The actual
'working' results were incredible.

The Saturn V used F-1 engines, not LH2/LOX, for primary boost. I
regret that it's production was stopped. Stopping production was a
money saver, supposedly. A false savings.

How was it 'originally' conceived?
It sucked up too much money because it flew quite often. It flew quite
often because it was needed for satellite insertion, repair, and
retrieval. Corporations paid for this. Money, one way or the other,
was allocated for military missions.
