NURBS Primitives Airplane First Model

I started this model by creating a rectangle from the NURBS primitivesmenu.  I selected specific points on the lower left side of the rectangle and pulled it in to give it a curve.  I also did that on the tail wing, to give it a more aerodynamic appearance.  I added two sets of rectangles to make up the wings afterwords.  I made a sphere and cone to represent the cockpit, and the nose of the plane respectively.
