Continuity mistake: When Dusty first takes off for the big race his "D7" on the right side of his tail disappears. (00:32:35)
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.
Other mistake: In the regional qualifier, there are five planes with better times than Dusty. Fonzerelli is disqualified. So... How come the other four that qualified don't show up in the big race?
Continuity mistake: Throughout the movie Skipper's rudder is a Navy blue (black?) and white checkerboard, but when he completes a flyby at Dusty's final victory the rudder is red and white, and the damage is different from when Ripslinger sliced him in the desert. Later, as Skipper and Dusty launch together off the USS Flysenhower, Skipper's original color scheme has returned. (00:21:10 - 01:20:36)
Continuity mistake: When Dusty is being pulled through the tunnel before the first Wings around the Globe race, he has a small Skull and Crossbones logo on his front cowling just behind the prop. The camera cuts away, and then cuts back and the Skull and Crossbones logo is now gone, by the time Dusty is next seen outside, the logo has reappeared.
