Korea: Buffer Zone Set As Prelude to Truce. Allied and Red negotiators agree on a buffer zone approximately on the present battle line, but the U.N. command takes no chances and crack paratroops conduct extensive jumps behind the lines. Communist and United Nations delegates walk past guards, snow on ground, into tent for meeting. Men make markings on a large map while a few photographers press in for a shot. Exterior, paratroops gear up. Air to air shots planes flying over water and land. VS paratroopers pouring out of the airplanes. Troops land (look like fairly hard landings).
