a lot of this stuff has been disproved... the author made a lot of the "wtc2001.com" website being registered "so some people must have known what was going on"....shame he never noticed (i.e. never bothered to look at the site; or did, and didn't mention what he found there as it would dispel one of his central theories) that in this case it means "world track championships"; a cycle race....

is it a coincidence that this story was published on april 1st?

 http://www.wtc2001.com if you want to look yourself

did clock the date about 2 minutes after pressing the publish button and thinking about the Thierry Mayssun/Perry Mason connection, so yes -gullible before 12 noon.
Still presuming 'the Italianate hilltop village to be Barnsley rebuilt' isn't the fool story, I would posit 3 explanations:
1. A dastardly plot by the Guardian to equate conspiracy theorists with believers in stories about spaghetti trees- an old april fool number - so the first time you mention alternate theories to those to the 'axis of trustworthiness' propaganda of Bush/Blair in 6 months about the events on 9-11, it's all a joke, and anyone who believes it is a fool
2. It's the only way to present an element of alternative ideas on the news pages and get past editorial censorship.
3.The editor would seriously like to publish alternative ideas but daren't and this is the only way to leak something out
The French originated Pentagon story was always possible disinformation - the 4 frames available to view could present a blur of a passenger airliner, but equally, you could see the shape of small fighter jet on one of the frames. It doesn't really matter in the face of all the other evidence regarding the WTC and all

and you're so daring, so print this wholesale, fucking Guardian hacks, if you dare.
