Looks like they are getting close to stability with this model. I have seen this design fail a lot and really don't trust it yet. I still like Burt Rutan's group design - Spaceship One. Simplistic and already got to space.

Me too. Wings are old school, but they work great when the engine quits. This thing looks like a gum drop and if something goes wrong I can see it screwing itself into the center of the earth in no time.
