Airship

Some time after the fall of the Master, the Brotherhood of Steel constructed airships (zeppelins) and dispatched them to the East, to track down and assess to the extent of the remaining super mutant threat. However, a great storm broke the main airship and flung it far from its course. The mighty airship was badly damaged. The smaller sections were torn from the main craft and never to be seen again. Many of the Air Convoy leaders, including Paladin Latham, were lost to the winds.

The fraction of the crew that still survived, struggled to keep their ship aloft before finally crashing on the outskirts of the ruins of Chicago. The survivors eventually formed the Midwestern Brotherhood of Steel, a new organization, which diverged greatly from the ideals of the old Brotherhood. Latham's zeppelin crashed near the area later known as Osceolla, where he established his main base after he became Gammorin, leader of the super mutant army.

Appearances in games
