The World Trade Centre was also built to withstand the impact of a commercial airliner. The world is also full of the crumbled ruins of buildings designed to withstand earthquakes, but which collapsed when the earthquakes actually happened. Either because the design was wrong, or because they were built by corrupt contractors who bribed the politicians and inspectors, or all of the above.
