About Undicisettembre

The Undicisettembre blog was born in 2006 on the initiative of the IT journalist Paolo Attivissimo to deal with the spread of conspiracy theories about the attacks of September 11, 2001. The blog was initially aimed at showing how alternative theories were based on errors in the application of physical laws and often also on the bad faith of authors who exploited the emotions of the public to sell DVDs, books, T-shirts and gadgets of all sorts.

The first publication of Undicisettembre dates back to 6 July 2006 with this article. Over the years the site has evolved and moved on to the historical reconstruction of the events, collecting interviews of survivors, rescuers and witnesses, and to the investigation of the real gray areas of 9/11, such as the involvement of individuals linked to the government and the secret service of Saudi Arabia in supporting terrorists in organizing the attacks.

As of today, the website is no longer a group project, but is managed solely by Leonardo Salvaggio (formerly known by the nickname Hammer), a computer engineer by profession and an investigative blogger and YouTuber as a hobby: Linktree.
