When the bad guys have loaded Blu & Jewel onto the plane & are taking off, Linda & Julio are on the runway in the carnival float. The lead badguy tells his henchman to "pull up" & the henchman does so. The camera angle is then from outside the plane where it is seen that the elevators (the "flap"-like rear of the wings) flip down. Problem is, when the elevators flip down it puts the plane into a dive, not a climb. They should have gone UP to make the plane lift off the ground.
