However the international standard for what is considered the boundary for space is the K

True, but the Thermosphere cannot "really" be considered true space since there is still a semblence of atmosphere that is heated up to over 2200C (even though the molecules are too sparce to actually generate that temperature which still remains well below zero). Similarly the Exosphere is replete with helium, hydrogen and simple oxygen. At the end of the day, the Thermosphere and Exosphere does exert drag (albeit very little)Of course, gravity being the weakest of the four forces, is effectively negated at 50nm AGL, the curve of the earth is clearly visible, airfoils become useless and the atmosphere is thin enough that your blood would boil if you were to step outside of your aircraft without a pressure suit.Even though the Karman line defines space, one does not truly seperate oneself from all atmospheric influence and / or drag until one excapes the Exosphere. :-)Now, lets talk quantum singularities and ten dimensional physics :-lol

TONI!!!!!! Where ya been man? Drop me an email sometime stranger! :-)

>>Hi>>>>CS=Throwing good money after bad.>>>>Try this instead.>>>>http://orbit.m6.net/mirror_m6.html>>>>Final word.>>>>>>Pete>> Are you telling us that the Shuttle is simulated in Orbit?>> Craig>Orbiter gives you the shuttle from launch to docking with ISS, re-entry and landing as well as Mecrury, Gemini and Apollo. Also just about any space craft that's ever flown and a lot that haven't including some for the Scifi fans.Near future TOKAMAK fusion drive Vespucci in Mars orbit.http://forums.avsim.net/user_files/165955.jpgGraphics aren't up to FSX standards but the realistic physics makes up for that. Very realistic flight physics with a very STEEP learning curve. Be ready to spend some time learning how to get to ISS.

>Would not agree with you, shuttle landing is quite>challenging. And just take a look,what a beauty!>http://www.fs2004.com/forums/index.php?showtopic=101340&st=0By posting this highly edited shot what exactly are you disagreeing with me on, kind sire? You fail to actually state anything after "i disagree". I suppose sometimes the expectancy of a coherent reply is too far and out of reach for one to be constructed. The landing is "challenging" (no it's not) because you are dropping down like a piece of lead looking through a small window trying to locate some airport down there. Get an F22 high up, shut off the engines and glide it down. There you go. Instant space shuttle :)
