Can't wait to see the blooper reel on this one. I wonder where the
mistake took place here? You would think that after 24 (!) successful
landings of first stages they would have this down a little better.
But still, getting the staging of the side boosters done correctly and
without mishap is the bigger achievement in my book.
And all this done with two side boosters that had *already* flown
once. What a great event to be able to watch live.

Yeah, that's what it came out as.
