I'm currently sitting in the airport and my flight leaves at 7:50  basically, I'll be able to watch most of the countdown but not the actual launch.

Sorry to hear that! There's always watching the recording later, though. I had to do that with the SpaceX launch.

Yeah, the gf suggested that. We'll see if she wants to watch a whole rocket broadcast when I get into town since I'm going to visit her.

Welp, they had a bit of a problem and delayed it... then they delayed it again...

Third time's a charm, though! T-10 minutes!

Tomorrow, then!

Aircraft fouled the range....man this is stressful

[StupidAndy]

[Scotius]

Boats, aircraft... is there no place and time for a rocket to launch peacefully? But hey, at least thank to the delay i have another chance to see the launch live

[Mad Rocket Scientist]

T-30 minutes, and everything looks good.

Well, it is also in the OP...

About fifteen minutes! I hope it doesn't get delayed again!

Oops, I missed that.  Spaceflight now still has yesterday's stream.

Atlas and Centaur did their jobs.  Spacecraft separation complete.
