WTC-1, regardless of the fact that it is a result of a compromise, is a solid design to the parapet. The real issue is the unclad spire, and in my opinion, the unclad communication rings as well. People here seem to conveniently forget that the original intention of the spire and base (correct me if I am wrong, NYguy) was to create a "complement" to the Statue of Liberty's torch. To that end, not only is the radome on the spire crucial, but the original radome covering the communication rings which serves as the "sconce" which holds the "flame" of the spire.
These images show how far away the top of WTC-1 is from the coherent package of SOM's original design. Its actually like the frog and boiling water analogy as the architectural elements were removed piece by piece over time. If CTBUH counts this "thing" as a spire, then Willis towers' antennas should by all logic and reason be counted as well; otherwise its just willfull, blind patriotism like Traynor said...
