What is the name of Charles Muntz's airship in Up?

Charles Muntz’s airship in Up is called the Spirit of Adventure. The enormous dirigible serves as the home and command center of the famous explorer, who has spent years searching for the mysterious bird Kevin in the Venezuelan wilderness.

The airship appears after Carl and Russell encounter Muntz at Paradise Falls. Carl idolized Muntz as a child because of his celebrated expeditions, so seeing the Spirit of Adventure initially seems like the fulfillment of a lifelong dream. That admiration changes when Carl learns that Muntz has become dangerously obsessed with proving the bird’s existence and has attacked other explorers.

The Spirit of Adventure is more than a spectacular vehicle: it represents Muntz’s isolation and his refusal to let go of an old heroic image. Near the end of the film, Carl, Russell, Dug, and Kevin use the airship to escape Muntz and return home. Viewers sometimes confuse its name with generic terms such as “zeppelin,” but the film gives the vessel the proper name Spirit of Adventure.
