Might be the same. The only difference that strikes me is the colour of the big fuel tank...white in Tony's pictures and orange in the Orbiter site's screenshots. This free Orbiter sim keeps surfacing at various forums, and from what I can tell , has quite a dedicated following around the world. Might well be worth a dabble.
Well I tried this on a friends machine and as a long time, both occasional user of Orbitor, IMHO Orbitor it offers a whole load more scenarios and add ons than this new sim and doesn't really loose out anywhere. As for the difference in tank colours I think the first Shuttle mission featured a white tank and then it was changed after that. So that may be the difference? See below.
