Creating a complete airplane model in 2D isn't straightforward because airplanes are inherently 3-dimensional objects. However, you can generate some basic 2D views such as the top view and side view using OpenSCAD by projecting a simplified 3D model into 2D. Here’s a simple example to get you started:

```scad
// Helper function to create an ellipse
module ellipse(a, b, thickness=1) {
    scale([a, b, 1])
        circle(thickness);
}

// Main fuselage from side view
module fuselage() {
    linear_extrude(height=2) {
        polygon(points=[
            [0,0], [0,10], [1,11], [10,12], [25,14], [50,16],
            [75,14], [100,12], [105,11], [106,10], [106,0],
            [105,-1], [100,-3], [75,-4], [50,-4], [25,-4], [10,-3], [1,-1], [0,0]
        ]);
    } 
}

// Main wings from top view
module wings() {
    linear_extrude(height=2) {
        polygon(points=[
            [20, 0], [60, 20], [80, 25], [60, 30], [20, 50],
            [15, 45], [35, 30], [15, 20], [20, 0]
        ]);
    }
}

// Tail wings from top view
module tail_wings() {
    linear_extrude(height=2) {
        polygon(points=[
            [10, 0], [30, 10], [35, 10], [35, 15],
            [30, 15], [10, 20], [5, 15], [5, 10], [10, 0]
        ]);
    }
}

// Vertical stabilizer from side view
module vertical_stabilizer() {
    linear_extrude(height=2) {
        polygon(points=[
            [0, 0], [10, 4], [12, 15], [10, 16],
            [0, 14], [0, 0]
        ]);
    }
}

// Assemble the airplane parts in 2D
module airplane() {
    translate([0, 0, 0]) fuselage();
    translate([30, 8, -1]) rotate([90, 0, 0]) wings();
    translate([90, 8, -1]) rotate([90, 0, 0]) tail_wings();
    translate([98, 14, -1]) rotate([90, 0, 0]) vertical_stabilizer();
}

// Create a projection from the 3D model to 2D plane
projection(cut=false) {
    airplane();
}
```

Steps:
1. **Save the code above in an OpenSCAD file (e.g., `airplane.scad`)**.
2. **Open the file in OpenSCAD**.
3. OpenSCAD will render the 2D projection of the airplane model.

This model is very simplified and intended to give you a starting point. You can expand it with finer details and more realistic proportions.
