Unfortunately - and as David mentions - this is likely an initialization 
problem. Tony deals with initialization, but he is very busy at the moment and 
I don't want to bother him with this for a little while. OTOH, I really need to 
dig into this a bit more and understand it - and to some extent I have. 
However, the code on the FlightGear side that sets up the FDM initially and 
sets in motion the initializations (note the plural) is something I have not 
understood, yet. I have a hunch that JSBSim gets initialized properly at some 
point, but then is once again re-initialized superfluously and ambiguously and 
that's when things go screwy. The initialization is not optimal nor is it 
intuitive (to me). Any help or explanation in this matter would go a long ways 
in helping us.
