another company is still in development (in other words NOT released yet). Their aircraft can shoot at, but not destroy, AI aircraft in FSX and that's why they are doing another company. So that does really mean it has not been done before. If another company was released already, then Captain Sim would be wrong. Captain Sim Weapon for FSX is here now. And man, oh man, is it FUN. ;) Mark

Yes, indeed you're right here.
But now i'm wondering if it's also possible to destroy Addon AI aircrafts like the ones from Ultimate Traffic 2007, or is that only possible with default aircrafts?
Also i'd like to know the same about buildings.
