Found this on Steam
Greenlight. It looks good and I believe I read somewhere on Kerbal Space Program Forums that its a one-man developer. At first I thought this was a distribution attempt of that older sim "A-OK Wings of Mercury" but its not. I seem to remember another shuttle sim that came out some years ago and a member here flew it and would post screenshots.
But this is a different project using the Unity engine. Like I said it looks good though I wouldn't be into it for the VR but just the normal simming experience. We may want to head over to Steam if you use it and vote it up so that we see more and more of these kinds of products in the Steam market place. They have a Kickstarter page as well.
