The article is written by an English professor, and its greatest logical pitfall is a misunderstanding of how science works. Hayes dismisses as "physical minutiae" the scientific demonstration that the official version of events was physically impossible in its broad outline. The central fact is that the way in which the Twin Towers fell - sudden, symmetric, with a rapidity that implies zero structural resistance - is not consistent with airplane impact or localized fires. Most readers of Op-Ed News know that there was a third tower that fell in the same way, looking to all the world like controlled demolition, and for which no official explanation has even been proposed.
Activists in this area will want to seize this crack in The Nation's shameful complicity in cover-up of the 9/11 story, and express their views both to The Nation and to Dr Hayes.
