Lift off is after 16mins-ish.
This is the nerdier version with just the technical commentary.
There's a more entertaining version but every time the commentary gets interesting, it's drowned out by all the whooping/applause. Basically it sounds like a Jimmy Fallon episode.
[edit: I don't want to sound like a grumpy shit. It is SERIOUSLY stunning that they can do stuff like this - it's just a really crappy audio design choice]

I knew it was happening but I figured I'd be damned if I was getting up at 4am to watch it.
24:40 for the good stuff.
