”The events of September 11, 2001 have sent shock waves outwards as few others have in recent history. As a dark cloud of soot and dust settled over lower Manhattan, geographies were irrevocably changed as if there had been an urban eruption Krakatoan proportions. This set of destructive acts have challenged our imaginations and evoked numbness and sorrow no matter how critical an analysis of U.S. foreign policy one subscribes to.”
– Robin Keams in New Zealand Geographer (2001).
”The enormity and sheer scale of the simultaneous suicide attacks on September 11 eclipsed anything previously seen in terrorism. Among the most significant characteristics of the operation were its ambitious scope and dimensions; impressive coordination and synchronization; and the unswerving dedication and determination of the 19 aircraft hijackers who willingly and wantonly killed themselves, the passengers, and crews of the four aircraft they commandeered and the approximately 3,000 persons working at or visiting both the World Trade Center and the Pentagon.”
