Live video here:
which isn't official but I'm enjoying it; the commentators aren't idiots. The launch is about 40 minutes away if things go well and if they go really well the 2nd stage should land near me (well, about 300 miles away) but I have my umbrella ready in case they get things a little wrong.
There are other live streams right now, including a so-called SpaceX one that is trying to sell me bitcoins, but hope the launch goes well and those interested can watch it live. I think most people here are intelligent enough to find what they want to watch.
