Commerce, are largely conservative Republicans. At 9:10 a.m., Kennedy takes his place in the hotel's grand ballroom for the scheduled speech, and the First Lady arrives amid loud applause 15 minutes later. After the speech, presidential adviser Kenny O'Donnell informs Roy Kellerman, the Secret Service agent in charge of the trip, that the presidential limousine should not be equipped with its bubbletop if the weather is clear in Dallas. Later, press secretary Mac Kilduff shows the Kennedys a negative advertisement published in The Dallas Morning News with the headline "Welcome Mr. Kennedy to Dallas." Kennedy tells his wife: "We're heading into nut country today." November 22: Arrival in Dallas On Friday, November 22, 1963, at 11:38 a.m. CST, Kennedy, his wife Jacqueline and the rest of the presidential entourage arrive at Love Field in northwest Dallas aboard Air Force One after a very short flight from nearby Carswell Air Force Base, west of Fort Worth. The motorcade cars had been lined up in order earlier that morning. The plan is for the motorcade to proceed from Love Field through downtown Dallas before arriving at the Trade Mart at a 12:15 p.m., where Kennedy is scheduled to deliver a speech and share a steak luncheon with local government, business, religious and civic leaders and their spouses. Invitations for the event specify a noon start time. The motorcade does not depart Love Field until approximately 15 minutes after the party had arrived there, as the president and his wife take time to shake hands with many of the enthusiastic supporters. Dallas/Fort Worth's television stations were each assigned separate details. As Bob Walker of WFAA-TV was providing live coverage of the president's arrival at Love Field, KRLD-TV's Eddie Barker was set to broadcast from the Trade Mart for Kennedy's luncheon speech. KTVT had originated live coverage of the breakfast speech in Fort Worth earlier in the day. On hand to report the arrival on radio is Joe Long of KLIF-AM.
