Canada resisted helping U.S. on September 11
Excerpted from front page article in today's Wall Street Journal: "Within two hours, all of United's and American's domestic flights were on the ground and accounted for. Late in the afternoon, however, United still had some planes over the Pacific. These were nerve-racking times. United said it had to press hard on Canadian authorities and even Alaskan airport officials who initially refused to let the planes land."
