I read about this interesting glider a few years ago and haven't
heard too much lately. Does anyone know if this project is close to
production.

It is not close to production, but they have been delivering since about
a year. The ship costs something in the range of $ 250 k. Somebody who
flew the Antares commented like this: "You can describe the glider in
two sentences: 1) It's far too expensive. 2) It's worth every penny."
