This is simple quest where you have to find a missing pilot.
There is a wreck of an airship, and a few mobs wandering around and the pilot is slightly further north of the airship.
The pilots sword is lying on the eastern side of the airship.
The quest intends that you find the sword first and then the pilot, but its fairly easy to do the reverse, ie find the pilot first and then the sword.
If this happens, the quest will not complete, and you have to do it again.
Its not actually clear in the instructions that you have to find the sword first, as the quest merely says look for clues as to the pilots whereabouts.
