While the dwarves were developing their own flying machines, the gnomes simultaneously introduced a new model of static wing flying machine, the gnomish bomber (likely based on the earlier single-winged gnomish sky-engines used during the Second War). Produced in significant quantities and distributed to many gnomish and dwarven fortresses, the production of this craft was interrupted by the fall of Gnomeregan to the troggs. This device would have been added to the Alliance military force sometime during the third war, hadn't the troggs invaded Gnomeregan and caused the Gnomes to withhold their military and air force. Many were left in their hangars when the gnomes evacuated the city.
