Dusty's antenna is knocked off in flight over the Pacific Ocean. In the next scene, just after he's intercepted, his antenna is intact and clearly visible for a few moments.
In all shots of Skipper's tail from the side, the primary color pattern is red and white squares except when the tail is chewed up in the desert/canyon sequence. The color pattern here is entirely black or dark gray and white. In New York, the primary pattern is again red and white.
Going by the movie's logic, the USS Flysenhower's CO and LSO should have been planes rather than forklifts, as the navy requires aircraft carrier COs and LSOs to be naval aviators.
When Dusty is talking to Ishani in Nepal and he mentions her 'new propeller' as Sky Slicer Mark 5, made exclusively for the Ripslinger racing team. The propeller is a four bladed prop. None of the Ripslinger entries (Ripslinger, Ned or Zed) are using a four bladed prop. Ripslinger uses two counter rotating two bladed props. Ned and Zed each use a single two bladed prop.
Two left wings from a T-33 are delivered for Dusty's repairs.
When skipper is pulled out of the water in the flashback, the hull is clearly that of a nuclear carrier ( note the edge of the runway on the side ), which wouldn't be in service yet during WW2 .
In the closing credits, "The Girl from Ipanema" composer Antonio Carlos Jobim is credited simply as 'Antonio Carlos'.
In Skipper's flashback, a Jolly Wrencher sees an enemy ship and Skipper calls him Jigsaw 2 when he has a 3 painted on his side. Often an airplane's radio call sign is different from its visual identification number.
When Dusty is looking at the map showing the route of the "Wing Around the World" race, all the continents are labelled in large typo, except Europe, which isn't mentioned.
