Objectivity 
I realize this is a very controversial topic, but this article is simply not objective enough, and simply demonstrates American public opinion. For example, it is commonly accepted OUTSIDE of the United States that the fourth aircraft was downed by the US military. It is possible that the US media has exercised self-censorship and so the American public doees not have access to this information, but deleting caveats such as "the 9/11 commission determined that...", or putting it under "conspiracy theories" simply destroys objectivity.
Could we not have this article explaining that it reflects the 9/11 commission's determinations, and have a prominent link to "Disputes with the official account"? This would, hopefully, avoid offending people's sensitivity to the subject by keeping controversies off the main page, but also thereby reflecting a wider opinion?
