How do they behave?
When describing the behaviour of freefall bombs (guidance type 5), the Nova Bible uses the phrase ' "weathervanes" into the "wind." ' - but what exactly does that mean? I suspect it means the projectile points in some specific direction, but what direction?
Also, according to threads here in the Developers' Corner, they're not used in the game because the AI doesn't recognise them - so why is it present at all?
