It didn't crap out here, they just decided to show an up-close of one
of the engines firing up... and they stayed with that for what seemed
to be a very long time when I would much rather have been looking at
the entire vehicle lifting off.

Gorgeous launch, from what I could see via the webcast.

Congratulations, Boeing!

Talk about red exhaust in comparison with the Shuttle though...this
sucker looks more like a Balrog than a gas stove.

Might be due to the ablative expansion nozzles on the
RS-68s coloring the flame.

And ascending from the Earth's surface to orbit on Lox/LH2...an idea
that was thought to be pretty much impossible in the 1960's.

Since the final RL-10 burn cut off early, that idea may not yet have
been completely proven possible . . . :-(

One of the earlier Delta 4's did it though.

Contrariwise: in the 1960s, it was taken for granted that all ascent to
orbit would soon use LOX/LH2. After all, hydrogen was a wonder fuel,
obviously superior to everything else. The only reason the Saturn V
wasn't all-hydrogen was that people were in a hurry and didn't think a
really big hydrogen engine could be developed in time. The two-stage
fully-reusable both-stages-manned shuttle was going to be all-hydrogen,
even for RCS and OMS.

No, just more expensive than if one uses kerosene. Also note that the
first stage had unexplained less-than-intended performance.
