Really. Do it. It is in a grand phase to see. And stop to think we, the United States of America, put people there. God darn that was a special time. and the engineers that did this was mostly with slide rules. I suspect many now do not know what a slide is. Sort of an advancEd ruler/calculater. No other country has done it. We did it multiple times. And done with the encouragement of the last nice demoncrat president. We did it.
