The sim is modelling aircraft in space correctly

Because there is no, or to thin are to carry the aircraft, it will fall down.

Quite why you want to fly a/c at impossible altitudes is beyond me. Space is for spacecraft. So get a space sim.

No,no,no I just was wondering if it was possible to make an X-15, or other high alt. fighters that could be controllable at that high, well maybe not at 9999999ft. up but just barly outside the earth. I'm not talking about a space sim here. And yes i know how an airplane flys thank you very much (I should being a Ret. RAF pilot)

Except there's no atmosphere for your engines to breathe, RCS controls are needed as the wings are useless in a hard-vaccum environment, and you need a nacigational computer to help you calculation tragectories unless your brainy enough to calculate the path in your head.

Sorry you're wrong! Space craft don't fly!! They are projectiles. They DO NOT have "Normal flight" as you say. They follow parabolic trajectories and are entirely dependant on the thrust input which only increases the angle of the trajectory which in space and here on Earth is influenced by gravity. THEY DO NOT FLY!!!!!!!!!!!!!!!!!

WRONG AGAIN!!!  I suggest that you read up on aerodynamics and ballistics before questioning the sciences. Projectiles and space craft are affected by the friction of the air and gravity. They ARE NOT aircraft and follow ballistic science NOT aerodynamic OK!!!!!

Before trying to give lessons to anybody and making yourself ridiculous, I suggest you read some physics books about modelisation of forces, movements etc...

Then eventually, you could try to implement a simulator program  to achieve your knowledge.

Finally, we may be able to discuss together in a more serious way.

Not exactely. I was speaking about flight modeling and general physics, not specifically about FS.
There is another simulator which is done with a real physic model, I never remember if it's Orbiter or XPlane, and lets you display the forces currently applied to the "craft" you pilot, either in space or in the atmosphere. It helps a lot understanding what really happens.

Uh. It's called the X-15, A-12 (and its varients), Dynasaur, Aurora, Boeing X-43, ACTS, U2, Space shuttle and NASP.

Although some of them can't fly into space, they are all capable, or rumored to be capable of flying above 100 000 feet. The only ones that can't fly into space are the U2, and the A-12.

So there, it dosn't matter if the space ships are aircraft or space craft, because there are them.

Only problem is: as soon as you have an engine, even a single one, you're not ballistic anymore.
For example, a stone that you have thronw away is flying ballistic. Also, a missile wihtout wings that runs out of fuel flies ballistic. But while its engine works, it's not ballistic yet.

Now, to spaceships without wings, it's the same thing: If they have no engines at all, then they fly ballistic, that is like a stone. But if they still have their engines, then they do not fly ballistic.

And about what you certainely intended to say: a Spaceship in orbit is flying ballistic. A spaceship going to orbit or leaving the orbit is not ballistic anymore.

Thank You for answering my question. What have I done, lol

That's right unfortunately. So far, we do not know if there is any possibility to simulate a rocket engine in FSX, nor the rocket orientation of the aircraft body, so those discussions are quite useless.

Let's hope the new SDKs will allow some gauges to do the trick...

I'll tell you what you have done......

...you have opened a can of worms, allowed a selection of "Newbies" in, and released examples of the very worst of humanity into a Flight Sim Forum, to create alarm and despondency amongst the Regular Members........!

A rare occurrence, since the birth of Simviation......!

Paul...Now keeping well out of the various on-going FSX Forum arguments/slanging match...8)...!

P.S....off to the Sim V "Cafe" Forum for a nice, relaxing, cup of tea and a bun... ...!

I beleive that the [ENGINE] configuration file in fs2004 had the option of "rocket".  If that is carried over and actually functions... that opens up add on development of low orbit spacecraft.

Why would Microsoft allow such altitudes in the sim engine if they did not intend there to eventually be access to those altitudes?

best,
