Ooops well I said it had been a long time since I saw it. I skipped over it and he rescued a fellow plane in a near crash, has a near crash and then crashes into the ocean.
"Dusty gets distracted from flying due to his thoughts about Skipper and ends up crashing into the ocean but is eventually rescued. He is flown to Mexico to his friends but he is severely damaged and may never fly again. Skipper confesses to Dusty that he did indeed fly only one mission in the Pacific theatre where his entire squad of trainees was killed in an attack on the Japanese Navy. Skipper was the only survivor, but torn by his guilt, he never trained another plane or flew again. Demoralized and heartbroken, Dusty begins to consider dropping out of the race, but is encouraged by his friends, Bulldog, Ishani, and many of his newfound fans to continue and they all donate parts to have Dusty repaired."
In the end it is a very heartwarming story but I guess you know your kids and whether they can handle that while flying
