Korea Truce: Gen. Harrison Takes Over As UN Negotiator. The long-stalled truce negotiations get a new American boss, as General Harrison replaces Admiral Joy as chief negotiator for the UN forces. With the departure of Joy, Harrison takes up the reins of frustrating bargaining with Reds. Admiral Turner Joy pauses to speak with reporters (no natural audio). Joy climbs onto a helicopter and leaves General William Harrison to give it a go. Nice ground-to-air view of a military helicopter.
