<Sorry...subject should say "ad">
The Enterprise was used for "Approach and Landing" Tests back in ~1977.
In that sense, it has flown. However, it is not operational, and has
never been in space. It is used a lot for pathfinder tests. I.e., after
you build a new piece of hardware that interfaces with the shuttle, you
use the Enterprise to check it all out before committing to an operational
shuttle. Although I have not seen it, I would guess that the AF ad was
showing the Enterprise being used to test out the new military shuttle launch
facility at Vandenberg AFB, CA.
