Hey you got it bro, I thought you'd like it. ;) Well, the reason we are falling is because at the point we are at the start of the entry flight the de-orbit burn has already taken place, and we are at about 120km high, and our speed has been reduced from orbital velocity.

My geuss is we'll have to slew the ship back up to around 300km, and slew forward to an orbital velocity of around 15,000nts.
I havent tried this mind you but im using info from my "other" simulator.
Let's see, uhhhh 300km coverted to feet is about 984,000ft, and as for speed we need about as I said 15,000nts. So try slewing up using the up command (Q) to 984,000ft, and then slew forward (keypad 8) to 15,000nts and see if that gets a stable orbit.

I'll try it tonite myself and see what happens, im kind of curious................ ::)

Hmmm, I looked in Wikipedia on this and here is what im seeing, some usefull info methinks.  :
