Funny how the article doesn't mention the X-37 at all, artist renders of which are still available at the Dryden photo gallery and it's listed as "1999 - present" (Although this gallery hasn't been maintained since 2005, so read that as 1999-2005+).

So it looks like it was initially being planned to be run as a NASA project out of Dryden.

Edit: Which I could have found out just by reading wikipedia rather than maintaining a encylopaedic knowledge of the old dryden photo gallery.
