I hate these statues head to my boys missions!! Any idea how to complete this one? I go to the mountain top and kill everyone then blow up the statue, attach the head to the helicopter provided. then I fly over to the drop off point. With the head attached to the helio you cannot decrease altitude without letting go of the head to get to the dropoff. If I drop the head over the dropoff and try to skydive toward the dropoff, it says I'm leaving the mission area and fails me. Any help would be much appreciated.
