You need to break it down into smaller steps.
1. Load the airplane
2. Load some obstacles
3. Get the airplane up and flying
4. Get some user input so they can control the plane's flight
5. Get some collision set up between the plane and the obstacles
6. Create an animation of your plane crashing (ie: the front end crumples and fiery red particles shoot out)
7. IF collision between airplane and obstacle THEN play crashing animation
Now to accomplish all these steps you'll need to do what dj BlackDragon said and learn all the DB commands that you think will be necessary to complete each of the above tasks in your code.
