You could try changing the lines 68 to 74 to this:

if(Input.GetKey(KeyCode.Q))
{
  transform.Rotate(0,-Acceleration*Time.deltaTime,0);

  //reduce the speed slighlty when the player makes the plane rotate
  rigidbody.velocity.z -= Acceleration * Time.deltaTime;
}

if(Input.GetKey(KeyCode.E))
{
  transform.Rotate(0,Acceleration*Time.deltaTime,0);

  //reduce the speed slighlty when the player makes the plane rotate
  rigidbody.velocity.z -= Acceleration * Time.deltaTime;
}

If this works then you might want to add a check to see if the forward speed is greater than a certain amount so the plane won’t come to a full stop in mid-air :wink:
