ONE LINE FLIGHT SIMULATOR by Gordon Murray Flight sims, eh? They're the biz! There's Fighter Bomber and Chuck Yeager's Advanced Flight Simulator, to name just two - real reach-for- the-skies (right) stuff. But wait, what's this? Could it be that a home-grown effort is about to rewrite the rule books and lay down its revolutionary new standards for all future flight sims to equal? Well, no, actually. As you might expect, the title is wildly exaggerated. But Gordon Murray's program ain't half bad, and as it's so short you've got no excuse for not giving it a try. Go on, get on with it.
