I've never looked into it, but I've always wondered how (or how much) control they have over those giant rockets. I know the space shuttle flies a very precise profile and rolls over at a particular point, so they must have some good control. But I have never thought about how that control is

Hi Curt, As far as I know, some of the early rocket models either had secondary attitude thrusters or deflector plates placed inside the main rocket exhaust. Modern types (i.e. anything from the 1950s onward) have used gimbaling main engines. If you watch prelaunch space shuttle footage, you

The first fault is inside the gpc code. As I said before, by my best estimation, gpc is algorithmically correct, but when we throw arbitrary real world numerical data at it, we can encounter some numerical degeneracies and that can blow up the gpc routines. I have no complaints if someone wants

Hello Heiko, does your local FDM still uses default approach fuel etc? But even if not, there should be no difference in the flight behavior. The only effect of the approach fuel level is (for a rotorcraft) within the gear solver. By the way: I would prefer to use the old default values for
