I'm incorporating it on my side right now. (I vote with you, Erik! ;-) We need to address two things here - and maybe they need to be addressed the same way when integrated within FlightGear (I don't know): 1) Reinitialize at some position and state, with the same aircraft. - This may not require anything more than setting initial conditions and reinitializing the aircraft at that position and state without deleting the entire JSBSim instance. This is preferable for JSBSim standalone, and I would think it would be preferable anywhere, but in another sense I can see that nuking the instance and starting from scratch might be appealing. This is particularly true if our startup process is very fast. 2) Changing aircraft and position/state. - This is a more complex issue and I do think it requires nuking the JSBSim instance and creating a new one.
