That was/ is a really great addon!FireFly docked to the ISS! Which Version of Orbiter?
The Station is a McDonnell Douglas study from 1970. It would launch on a Saturn INT-21 then telescope out. It would be spun around its centre of gravity for rotational gravity up to 0.7g - although this was planned only as an initial experiment and it would spend most of its life as a zero-G station.Oh! I'm very interested. What is this based on?
