How can i acess the isFalling boolean in another script and check if its true or false?

pragma strict

var rotationSpeed = 100; var jumpHeight = 8;

var isFalling = false;

function Update ()

{

 //Handle ball rotation.
 var rotation : float = Input.GetAxis ("Horizontal") * rotationSpeed;
 rotation *= Time.deltaTime;
 rigidbody.AddRelativeTorque (Vector3.back * rotation);
 
 if (Input.GetButton("Jump") && isFalling == false)
 {
     rigidbody.velocity.y = jumpHeight;
     isFalling = true;
 }
 

}

function OnCollisionStay () { isFalling = false; }
