The plane in this picture was much darker than your plane in your picture to begin with:

If you have access to Photoshop, learn to draw a path around the plane. It takes some skill to do it properly, and a considerable amount of time.
Next, convert the path into a selection. Once you have a selection remove the path.
Now you have a selection of just the plane. Adjust curves and contrast. It only affects the selection. Ie. the plane.
Invert the selection. Now everything is selected except the plane. Make the background a bit darker if you wish so the plane stands out better.
Invert the selection again, now the plane is selected. Apply unsharp mask. Now the unsharp mask applies only to the plane, the background stays unaffected. And so on.
