For the moon practice lander they used a rocket that always pointed down to cancel out enough of Earths gravity to match the Moons gravity. Neil Armstrong seemed to like it :D

They could do something like that.

Nit: the Lunar Lander Research Vehicle actually used a CF700 turbofan[0], not a rocket, to partially counter-act gravity.

It nearly killed him. I don't think anyone actually liked it, and I bet a lot of people in risk assessment went hard on the "nixon needs to prepare the death letter" story.
