I've been looking for a movie for many years, I saw it in the late 80's or early 90's. Its about a boy who goes back in time and I remember he goes to a store and aks for sugarless gum, he goes to McDonald's, he goes to a gas station, he sees his grandparents and eats breakfast at their house, I remember he was like in a farm and a there was a red plane. That is all I remember about the movie, I have no idea what the name was. Only my brother and I remember watching this.

That would not be Back to the Future?

No not back to the future, this kid was probably 12yrs old, I remember he tried to pay with a dollar bill at McDonald's or at the gas station, A cheesburger was like 1cent, no one recognized his dollar bill because he traveled far back in time,he went to a store and asked for sugar-free gum and the shop keeper told him that he cannot give him sugar for free and the boy left, that's how they came up with sugar free gum.--My brother and I saw this many years ago and cannot find it anywhere.

I think I found it: The Blue Yonder (A.K.A. The Time Flyer). Go here to find out: http://www.imdb.com/title/tt0088831/

OH MY GOD! This is it, Thank you so much.. I'm not going crazy after all
