Realistic 2D flight physics?

Hi. I'm trying to make a realistic 2D flight game.

This is my current code:

         if(Input.GetKey(KeyCode.UpArrow)) {
 
             rigidbody2D.AddForce(transform.right * 500 * Time.deltaTime);
 
         }
 
         if(Input.GetKey(KeyCode.RightArrow)) {
             
             rigidbody2D.AddTorque(-10 * Time.deltaTime);
             
         }
 
         if(Input.GetKey(KeyCode.LeftArrow)) {
             
             rigidbody2D.AddTorque(10 * Time.deltaTime);
             rigidbody2D.AddForce(transform.up * 100 * Time.deltaTime);
             
         }

This is of course not very advanced.

I was wondering if you could add some improvements to my script, or do you know about another 2D flight physics script?

Thanks in advance.

Andreas.
