It is one thing to calculate how much thrust an engine has to deliver, and another thing entirely to develop such an engine. And that can do it as sea level as well as in a vacuum/thin upper atmosphere!

Same thing with fuel. It is one thing to say "we have to deliver X units of fuel to the engine per second" and another thing to design a MASSIVE TANK that will deliver that fuel DOWN TO THE MILLIMETRE and MILLISECOND.

The Saturn rockets actually had this problem, the fuel would surge (on the millisecond scale) but this would result in uneven thrust, inducing vibrations into the rocket, and for the astronauts it was said to have felt akin to a 'atomic powered Pogo stick', hence the name for the phenomenon, POGO oscillations.

They used kerosene for fuel in the first stage and the incomplete combustion put on a hell of a show for the cameras. The engines that powered it never reached their full design potential because they didn't have computer technology advanced enough to control them and the vibrations shook anything attached to them apart.

In the end the obstacle was not the machinery to reach and return to the moon itself, but the inability to keep anything alive on such a trip. the Apollo spacecraft was totally incapable of such a feat, astronauts would have died shortly after the trans lunar injection burn.

The Russians laugh at us for believing it, btw, I likened it to the legend of Davy Crockett killing a bear bare handed when he was five, when we know the real story of Davy Crockett turned out to be one of defeat and ultimately shame.
