Almost all revolving doors in America are manufactured to be collapsible; that is, in an emergency the "wings" slam together to create one partition, allowing more traffic to flow. From Wikipedia: "In 1943 it became Massachusetts state law to either flank a revolving door with an outward swinging hinged door or make the revolving door collapsible (so it becomes a double partition collapsing at 180°) allowing people to pass on either side. American revolving doors are now collapsible."
