"Yes, the quaffing would be spectacular, at 0 g."
Actually it's better than that.
Skylon was designed to be statically stable in a way that Shuttle (and anything else that's got big point masses at the base, like any rocket stage) is not.
So it's designed to not need the continuous control surface "fluttering" you see in combat aircraft (that have either relaxed or zero static stability).
IOW it could be flown by a human without a computer between them and the controls.
Making Skylon (potentially) the worlds fasted human pilotable aerospace plane.
Which would be quite exciting so some groups of pilots.
