Get object to follow line render that can have trajectory manipulated

Question

I’m working on a project based off of the old flash game Steambirds. I’m trying to make a similar movement mechanic to the one in the game, with the ability to manipulate the aircrafts trajectory and have it follow the projected line when a turn is started. I’ve looked into it a bit but I’m somewhat stumped on how to accomplish this. Any advice or suggestions on the best way to do this?

Look at this code. Not tested though.

 class ChaseCursor : MonoBehaviour {
     private Plane plane;
     private Vector3 velocity;
     
     void Start(){
         plane = new Plane(Vector3.up, this.transform.position);
     }
     
     void FixedUpdate(){
         if (!plane) return;
     
         Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
         float enter;
         if (plane.Raycast(ray, out enter))
         {
             Vector3 endPoint = ray.GetPoint(enter);
             Vector3 thisToEndPoint = endPoint - this.transform.position;
             Vector3 acceleration = thisToEndPoint * 0.1f;
             velocity += acceleration * Time.deltaTime;
             aircraft.transform.position += velocity * Time.deltaTime;
             aircraft.transform.LookAt(endPoint);
         }
     }
 }
