Yes, we made a deliberate attempt to introduce unpredictability to the mix, rather than making planes that always acted and moved exactly the same. If you pretty much know a plane is going to move, you can move to avoid it. With a combination of "smart" movement and random movement, you never know how or where they're going to move, so you can't plan around it. Also, the Bandit "AI" is still a work in progress somewhat, so over time it will get better, and is modeled pretty decently already. The bandit might have been flying away from you to avoid being fired on, perhaps?
Hope this helps you, Joram!
