Yes! They held it!

I was worried I was 4 minutes late!

Now let's hope it still launches today. An umbilical arm issue might mean going up to the rocket to repair it, leading to a scrub.

Anybody who stopped watching after the initial launch missed the interview with world's stiffest, whitest, most monotone Air Force officer ever.

My comment was more about the delivery than the content. The flashy Boeing video was much more entertaining.

switched time to time to watching the video during the comments, the mimics :3 :3 :3, "proud proud but can't say too much stress stress, pressure pressure" ^^ :3 sort of ^^

first time i've seen a delta iv launch the ignit is pretty caracterisitic & impressive // some other launchers
