Has anyone got a spaceplane in orbit yet?

Thought it looked cool but a dud is a dud...

Someone made a SSTO rocket with 22% payload fraction...

Well, at least it provides an improved view for backseat pilots...

Well, I have managed (after many tries) to get an Aeris Mk4 (which I slightly adjusted to improved the center of lift compared to mass) into orbit and back. I leveled off and hammered it below 20k with just the air-breathers, until I was surrounded by flames. Then I fired everything, and angled up to 45degrees, which took me out of the atmosphere, having lost only my two forward canards. I made it all the way to a 270,000m circular orbit. Here's a pic to prove it:

Getting back was awkward, but I found that the key is taking a shallow entry profile and aerobraking as much as possible from 42k until reaching less than 900m/s. I just pitched up and down as much as I could, which seemed to work, but proper aerobrakes would be better.

And to make my success sweeter, I arrived right near KSC, purely by chance.
