Amazing technology, very impressive, a triumph of human accomplishment.
Landing on the moon was probably the most significant achievement man has accomplished, putting humans there is still amazing 43 years later but I'd rank this right up there.
The delay of mission communications was terrible, the mission may have ended tragically or was a success but the long delay relaying back to earth was a nail biter. I watched the final 20 minutes and I was terrified of failure, there were only what a million or more things that could have gone wrong with no way to know and correct anything.
