Hi,

	I have the code working for turning a ship around and flying manually but
what I really want is for my ship to be able to fly on autopilot. So if I
give it a destination X and Y it will slowly (1 in 10 module iterations)
turn to face the direction and fly there.

	I have 36 different directions my ship can face and that is all working
fine, I am just having a touch of difficulty with the logic.

	Any ideas? :-)

Tom.
