I agree that we should be patient. Look at it this way - it is far better to have to wait a few days more and get a good piece of code than have a bunch of problems from something that was 'on time'.
I ain't a programmer but I know enough from open source flight sims to see that this is a complicated piece of work too. To try and replicate complex physics with a few algorithims is almost like trying to play God - but with a whole lot less stuff to work with. I hope the Shipsim team keep going until it is right rather than giving in to pressure to produce a quick fix.
