Whoops! Missed DSGeorge's question above.... Can my starfighters participate in a battle at a external site? Sure, they participate. But you don't want them to. A landed starfighter has power=0 and its pilot may not apply ability toward drawing battle destiny, because he's not piloting the ship, it's just landed. Now, if you had other characters at the site during the battle, it doesn't hurt to have a useless starship sitting there, because during the damage segment of the battle you can just forfeit the ship, which may help you keep another character on the table. Hope that answers your question!
