I'm sorry  I can't think of the title,either. But if you are talking about same film, was a boy accompanied by his beloved dog after the crash?  Was there a scene where his father who searches a boy on another plane drops message on thousands of flyers in desert? It was more than 20 years ago when I saw the film at my elementary school screening. I remember that the dog didn't get rescued (but a boy was) at the end I was very disappointed. Am I talking about same film?
