In my attempt to get some good times out of the extra time I've wasted, I went back to an app I haven't seen in a few months: Orbiter!
I remeber this possibly making the rounds on the blog circuit in the spring of last year which was pre-typepad so hopefully some of the new visitors will apreciate it and any old visitors will remember a great app that's been continuously updated.
Anyway, The picture shows seperation from the main tank at T+8:58 which by the manual is supposed to be 110km above the earth. Mine was more like 1500km, probably because I didn't roll into a path for my suggested orbit. The manual states

"Roll shuttle for required heading, and decrease pitch during ascent for required orbit insertion."

I'm not quite sure on what either of those numbers should be for me to be in a fairly normal orbit so I just kept going up :)
This is not your average flight sim. There are no explosions, you can't kill things and if you hit the earth, you bounce. BUT the physics are amazingly accurate and the flight is very realistic. Subsequently, it's not very intuitive. You're better off going through the manual at least twice and then starting to try things on your own.

It's awesome to be able to put yourself in orbit or dock with a station though. And it's highly modable! Go have some fun...
