OpenGL is hard to master, so you are a bit in trouble. OpenGL is for drawing, so you need some data model of the airplan which than gets transformed and drawn. And you need some input and output elements for the game control. That isnt OpenGL but some other library like Qt or others. Maybe this OpenGL tutorial helps you.

I have provided my experiences in How to start a homework. Important is to structure your code in classes and structs which helps you to organize the work.

There are also several useful articles about OpenGL programming on this site. Most of them deal with the old-style of OpenGL programming with the fixed pipeline. While that is obsolete and outdated now, it is probably the way you should go since it is quite a bit simpler than the modern style of OpenGL programming.

Here is one very interesting sample program : 50 OpenGL Win32 Projects in One[^] It is for windows but there fifty projects in there and one of them might be close to what you are after. At least you get a lot of code to look at. I would find a windows machine and try to run that program to see what it has if I were you.
