Continuity mistake: Dusty Crophopper is on the USS Flysinhower being brought back up to flight deck on the aircraft lift. At this point the lift is fully surrounded by a raised barrier (poles and rope/chain). In the next close up shot (before the lift reaches the flight deck) the barrier has disappeared. The barrier should only retract into the deck of the lift once it reaches the flight deck (and not before) as it's to stop people and aircraft going over the edge.
