Ok I decided to give this craft a thread of it's own, and since it is a fictitious one(tho based on a real one which I will show also) I thought it belongs here since it is also freeware as well. It was featured in the last stages of "Battle of the Airlines" 2003 in which virtual pilots from all over the globe battled in a race that took place in 8 stages over an 8 week period and this was the plane we flew in stage  7 where we were to transport a shuttle craft on it's back to Kennedy Space Center Florida to be launched on a flight to the moon in the final stage.

Now this is the real SST that it was based on,(well, sort of) and is built by as I believe, Rockwell. And is operated by NASA & the USAF. A very talented fellow who goes by the name of "Ace Lomcevack" designed and made the "SR75" pictured in the post above and he has a site where these and many other projects he has as well as some cool scenery is called "Aeroworks" at http://www.simviation.com/aeroworks/
I was proud to have been a contestant in that race, and to have had the oppurtunity to know Ace, and his work. Also to have known the 1500 or so pliots who competed in "Mission Moon"

Hmm, ok how bout this one.............

I had to fly this thing with an engine out, and land it in Havana, Cuba of all places Heh, heh,......when that engine blew I bout jumped through the roof and had to change my britches when i got to Cuba!!

Well this is weird, I saw these files on several sim sites awhile back, in fact the whole Mission Moon pkg. was availible, and you could do the whole race yourself. But I just did a search and cant find any of them.............Hmmm, I'll have to do some digging.
You might try at the Aerowoks site from the link I put in the second post, and e-mail him, but heck I couldnt even find the planetaviation site that hosted Battle of the airlines..............weird ???

While I don't really know, the name suggests it needs air.

I knew this would draw your attention Rifleman,
Well this was just an image to advertise the race, we didnt fly it to the moon in that configuration, the only time we flew it in this cfg. was at launch just as the real one does. And even then, there was no actual boosters propelling the launch vehicle, you see these flights were being controlled by a program written by the team that invented the race, and it had complete control of things as it were.
The flight actually was in slew mode, and when you reached 100,000ft the program running the flight simply loaded a new flight at that point, and then you found yourself in orbit, which actually you weren't but rather somwhere over Africa, at night, with no moon in the night sky, at about 40,000ft and in slew mode so it seemed like you were in orbit. It was an ingenious thing really that these talented individuals did with this program which ran fs2k2 from outside fs2k2, using FSUIPC and the visuals that they had in front of you it really was like being in space 8) After we docked with the ISS in orbit, we then made our flight to the moon thru a "Worm Hole" which was actually just a piece of scenery that you flew to, and then the program would again load another flight in and then you seemed to come out on the other side just above the moon's surface. But once again, you really weren't, you were still in the same place 40,000ft over Africa at night but with moon surface tiles(daylit) overlayed on the ground.
As I said, it was simply ingenious what these talented fellows did with it.

No problem Rifleman, hehe, i strayed someone else's with this to start with (an unusual Concorde) heck yer welcome to my threads anytime and since yer thirsty, here.......have a drink, it's Jawa juice courtesy of the pub I visited on that moon trip.
