Some U.S. officials have speculated that September 11 planner Mohamed Atta, who piloted American Airlines Flight 11 as it crashed into the World Trade Center, traveled, to Canada through Portland, Maine, on the eve of the attacks to meet with his "handler." There has been no other explanation for his Sept. 10, 2001, trip to Portland, from which he could have taken unchallenged the Quoddy Loop ferry line into Canada.
