By the time Cross first arrives in New Los Angeles, Lin has been working on development of a Skell flight pack for some time with little success. It is completed during the affinity mission A Girl's Wings, which becomes available after Chapter 9, and Vandham renames it the Skell flight module. The flight module is automatically equipped upon acquisition, and removing it is not possible. It is incorporated into all Skells after the mission is completed, including those already owned by the party. During flight, the song Don't Worry plays.
