The earlier flights were not done in a re-usable spacecraft.

So what?

So that is a large part of what makes it different from the single-shot
suborbital flights of the past.

Not to mention the thousands of man-hours and cast of thousands needed
to turn around the shuttle.

One step on the road to non-government, gold-plated, decades-long
development projects type spaceflight.

The problem is that merely reaching the altitude is only a
part of the problem. The real issue is achieving orbital velocity
and the Rutan aircraft doesnt achive much more than 15%
of the velocity required to put something in orbit.

The X-prize doesn't require orbital flight. Only that it reach a certain hight
with 3 persons aboard and is repeated with the same craft within a specified
period.
