Sept. 24, 1961 - President Kennedy arrived in New York today to deliver a major speech tomorrow to the U.N. The President was greeted at La Guardia Airport's Marine Terminal by Secretary of State Dean Rusk and NYC Mayor Robert Wagner. Surrounded by 40 motorcycle policemen, the President's car sped into Manhattan at the head of a long motorcade. More than 1,000 policemen and an undisclosed number of detectives and Federal security agents guarded bridges, intersections, and roofs along the route. Two police helicopters flew over the Presidential car the entire way. Sizable crowds cheered and applauded Mr. Kennedy along the route and outside the Carlyle Hotel on Madison Avenue, where he will stay until his departure for the U.N. at noon tomorrow.
