laser is not working

I have a script that I have been working on for a while now. I have it almost done and ready to go. I have it so that it has multiple if statements in it so I can target different items and have it so that different things will happen to each item, or so I hope. It is not working out that way. When I fire the laser it goes toward but not directly at the object tagged Drone. It will not fire in any other direction. I need to know why that is. Please look over my script and tell me what is wrong with it. Thank you. using UnityEngine; using System.Collections;

public class Beamlaser : MonoBehaviour { LineRenderer line; public GameObject other; public GameObject explosion;

 void Start () 
 {
     line = gameObject.GetComponent<LineRenderer>();
     line.enabled = false;
 }
 
 
 void Update () 
 {
     if(Input.GetButtonDown("Fire1"))
         
     {
         StopCoroutine("FireLaser");
         StartCoroutine("FireLaser", .25F);
         audio.Play();
         
     }
 }
 IEnumerator FireLaser(float lengthOfTime)
 {
     line.enabled = true;
     var t = Time.time;
     
     while(Input.GetButton("Fire1") && Time.time - t < lengthOfTime)
         
     {
         Ray ray = new Ray(transform.position, transform.forward);
         RaycastHit hit;
         
         line.SetPosition(0, ray.origin);
         
         if(Physics.Raycast(ray, out hit, 1000))
         {
             line.SetPosition(1, hit.point);
             if(hit.collider.gameObject.tag == "Hand")
             {
             Instantiate(other, hit.point, transform.rotation);
             Destroy(hit.transform.gameObject); 
                             }
         }
         else if(hit.collider.gameObject.tag == "Drone")    
         {
             Instantiate(explosion, hit.point, transform.rotation);
             Destroy(hit.transform.gameObject);
                 line.SetPosition(1, ray.GetPoint(1000));
         
         yield return null;
     }
     line.enabled = false;
     }
 }
