Timer indication and flight Log Information

" />

Red circle=Helicopter icon, point1 is the location for helicopter to fly to follow by point2

Basically i am doing this new function(make New Flight log) This image show the places for helicopter to fly to. So i wanted to create somethings able to on/off the log. The log is able to display the distance from the helicopter starting point to the point1. as well for other point2 .... and also to display the time around that to reach it any1 has any idea. pls help me Thx below is script for the when i click to add waypoint 1 and formore.

//mouseclick to add waypoints

             if (Helicopter_Script.flightState == 0)
             {

                 if (Input.GetMouseButtonDown(0))
                 {

                     position = Input.mousePosition;

                     if (position != prevMousePosition)
                     {

                         prevMousePosition = position;

// Debug.Log("MouseClicked: mousePosition (x) - "+position.x + ", (y) - "+position.y);

                         if ((position.x>=20 && position.x<=570) && (position.y>=150 && position.y<=780))
                         {
