a wheel, and small bits and pieces, hardly definitive of a giant 757 filled with thousands and thousands and thousands of pounds of people and luggage and steel.

obviously it was some kind of 'air plane' or air craft. but explain to me how a 757 can make a hole in the side of a building smaller than the plane itself...and how a 'terrorist' who had never flown such a giant plane could fly with such military precision...
