Teams are ecstatic to trade their car keys for plane tickets to their next destination out of the country.

The five families travel to Mesa, Ariz., where one team member must take the controls of a fighter plane and complete a 360-degree loop in the air. Next, the teams drive to the Grand Canyon and then to the Glen Canyon Dam, where they must choose between bailing water out of a submerged boat or using a compass to find three clues on a river. The teams then race to the pit stop located aboard a houseboat on Lake Powell.
