After the families compete in a pie-eating contest as a prize challenge, they go hot-air ballooning in New Mexico. Next is an immunity challenge in which they must seat mannequins on an airplane, with the top family being flown ahead to a luxury resort in Phoenix. The bottom three families must go through an elimination challenge at the Meteor Crater in Arizona, where they must correctly identify various flying objects which are projected through the air.
