Need help, not having luck explaining whats happeing

OK, I am definitely new here. And have once again started trying to learn. And I have run into an issue. Im testing a mesh plane that was a free model online to see how works.
I am using the starter project for flying. I imported the mesh. Replaced the spaceship mesh with the plane.

My issue is the model is flying sideways.

  1. I moved the camera around to have it behind the plane. Now the camera and plane are moving sideways with a rear view of the airplane.
  2. I move the camera back to default. I have a side view of the airplane. And the camera moves forward like it is supposed to. And the view is the side of the plane.

Any help please on what I did wrong.
