Check out this read over at Politico on the 15th anniversary of 9/11:
For the next eight hours, with American airspace completely cleared of jets, a single blue-and-white Boeing-747, tail number 29000—filled with about 65 passengers, crew and press, and the 43rd President, George W. Bush, as well as 70 box lunches and 25 pounds of bananas—traversed the eastern United States. On board, President Bush and his aides argued about two competing interests—the need to return to Washington and reassure a nation and competing need to protect the commander-in-chief. All the while, he and his staff grappled with the aftermath of the worst attack on American soil in their lifetimes, making crucial decisions with only flickering information about the attacks unfolding below. Bush struggled even to contact his family and to reach Vice President Dick Cheney in the White House bunker.
