Preparing for Take Off

Steps

 * 1) Go back to the hanging tower and disable 4 stones in various places around it. One on either side of main building up top and 2 on lower portion.
 * 2) Kill the officer inside and get key.
 * 3) Use the key on the chest inside the officers room, center of hanging tower (updates all group members on this step).
 * 4) Place bombs around the large chains on the outer edge of tower. The info window is kinda small to place the bomb at each chain base.
