Well, one is an aircraft made of aluminium, the other is a ship made of a hull made from continuous steel plate backed by forged steel ribs and horizontal steel decks etc.
A 767 is an aircraft made out of aluminium and the towers are made out of hollow steel columns.
If an aluminium aircraft can crash into a steel ship and break through the continuous steel of the hull, why can't a much bigger and heavier aircraft break through the columns of the building?
