For my nearly 5 year old who loves airplanes and has been a fan of "Cars" since he was 18 months old, the movie was great. Parents should know that there is one scene where one of the main characters, Skipper, a WWII F4U Corsair, tells the story of why he doesn't fly. In a flashback to WWII, there are ships with anti-aircraft guns shooting down his squadron with the implication that all of his squadron were "killed" except for him (again, this is just implied, not stated or shown explicitly). This was probably the only objectionable scene in the movie, since my son has never been exposed to gun fire before, but this was mostly over his head. Aside from that there is a scene where the main character, Dusty, crashes into the ocean and looks like it might be "the end", but he is quickly rescued by diver and chopper team.
