You have to take the Bombing quest on Quel'Danas Isle. If you fly you can Drop Bombs (But only in the Death sth. (I've got german WoW Version)). But If you only click the bomb without droping it before you leave the area, you can still hold the bomb and throw it! So you can attack mobs with faction 14 =)
It's very useless, but hope you like it =)
