Heartwarming / Flight of the Navigator

• Despite David being understandably freaked by that point. The obvious relief of his eight-year-older parents at getting their son back, was completely understandable.
• Sixteen-year-old Jeff is very supportive. That relationship was what made the movie. The way Jeff had completely changed — the way David suddenly had to rely on him, and how that worked. Jeff was so much looking out for David, even signaling him to get away at the end, and it made their reunion at the very end of the film all the more special. For a time, Jeff had been the Big Little Brother, and David hadn't forgotten it, and you could see how that memory had affected him when they reverted to their old roles in the end, and David was kinder to his brother and more willing to trust him, showing him what he'd obtained and everything.
  Jeff at 16: Don't take any shit, David!
• David and Max, just before the time jump to the past.
  David: Let's get outta here.
  Max: Compliance, navigator. Good luck.
• David reuniting with his present time family at the end.
  • The scene where David makes amends with Jeff. True to what sixteen-year-old Jeff said to David about jumping out of the tree and scaring him, present-day Jeff seems to feel bad about the prank, asking David if he was mad. What caps off the scene is David saying that he’s not mad and that he actually loves his brother.
  • The mischievous grin David gives Jeff when he signals to him not to reveal the Puckmarin to their parents. Though still clearly confused, Jeff happily agrees.
• "See ya later, navigator! Ha-ha!"
