Wow, you actually saw the moon missions live. You must be an old man.

Not to mention witnessing, in person, the launch of Columbia on STS-1.

I'm 51, so don't remember Apollo at all. But I do remember STS-1 and
beyond. STS-1 was ground breaking for its time. Unfortunately, the
press never picked up on the many things that went wrong with STS-1
besides perhaps the obvious missing silica tiles that fall off. Even
NASA still isn't terribly forthcoming about all of the issues. Cite:

No mention of the body flap (that was almost a very bad day) or the
flight control system issues. Here is a cite for the body flap issue:
