Navigator Fairweather pilots The Thundercaller, a zeppelin that runs between Orgrimmar and Brill. He gets a good workout running and operating all the switches below deck, all by himself. He'd like it if you don't bother him during flights. He will also tell you that he can't be blamed when the Thundercaller crashes, as he is unable to see what's in front of the zeppelin from his station below decks, and relies on the orders of Sky-Captain Cloudkicker.
Although he shares the same last name with Lieutenant Fairweather, they are apparently not related.
