It happened. It was an astounding, against the odds, seat=of-the-pants achievement driven by the quest for political supremacy. It wasn't the first. Wave after wave of maritime exploration and conquest, the vikings, the dutch, the poms, the spaniards, WWI aerial combat, are just a few. All, including the moon landing, had unbelievable human carnage on the road to pulling it off and were the result of superpowers competing for prestige, power and resources.
Saw the Neil Armstrong biopic First Man, amazing. Half the astronauts died in testing. Literally half. They were I'll-prepared but pulled the trigger to beat the Ruskies, and strapped a giant firecracker to a glorified EH Holden and lit ér up. Amazingly, to everyone including NASA, they pulled it off.
As others have said it was a dead end for all sorts of reasons, but that is beside the point of the historical context, it was about symbolism. And in spite of all the hindsight, (what were they thinking, they got lucky, what was the point etc etc which all has validity) the importance of the symbolism endures.
