Pitching.
What's that protrusion from the fairing?

Vent for hydrogen gas boiloff.

Fantastic, smooth launch! 

I haven't watched many ULA launches - do they always announce the engine model number like that when they fire? ;)

Was thinking the same thing. Maybe they decided Buran didn't qualify because it was designed to carry crew, whereas X-37 never was?

Ok, so that's the end of coverage. Ended with fashion tips. Bizarre! ;D

Webcast ends.

Congrats to ULA, the USAF and the many people who will get their cubesats into orbit!

Quite a refreshing change to see a launch success of late. :)

The nozzle "extension" on the RL-10C looked longer/larger than the A4--or perhaps better stated, the C1 nozzle looks different than the A4, and very impressive.  Materials sciences is a good thing--can't wait to see clusters of said engine working in concert...
Congrats to the teams, now on to mission(s) success(es)!

Congratulations to all involved in getting the only currently flying spaceplane successfully into orbit again.

Congrats to ULA for a good, solid, on-time launch.  It's what we're beginning to expect, every time.

That rocket cam was sorta weird, though.  Every time they'd cut to it, it looked like the Atlas was still climbing vertically up from the launch complex.  Even well after the vehicle was pitching down into its near-horizontal trajectory.  Made me wonder there, for a minute, if the thing wasn't gonna keep goin' straight up...  ???

Other duties kept me from watching all but the end of the ULA webcast...

Great launch replay at the end-of-webcast.

I enjoyed the Steve & Bill show!  They looked like they were having fun!

Well, and Dragon "returns to earth and lands" as well, as have a number of BEO probes (Stardust, etc).  I think they were missing the words "American" and "winged": "first American unmanned winged vehicle to return to Earth and land". The "by itself" is redundant, considering it is unmanned -- unless they are thinking of some sort of remotely-piloted drone?  But I don't think that's been ever been done, so the qualification seems unnecessary.

Yeah, I've seen that on other launches, like Antares for instance. But if you look, you can see the land start to foreshorten as she pitches over.
