I'm still in awe that I got to watch a reentry live stream just now. I wish I could tell my child self what wonders were in store. Watching humanity progress in real time is amazing.
Yeah, it's pretty awesome to watch "the first" of something! I wasn't born early enough to watch the moon landing, but I did watch the livestream of the first successful landing of a Falcon 9. Watching that bit of science fiction turn into reality was one of the more memorable moments of my life.
[Edit: I meant to be talking smack a bit, but don't let me ruin your enjoyment of the really amazing things that are happening now.]
