There are a number of organizations that challenge the official story (as in fairy-tale) about what happened on 9/11/2001 in New York City (see this for a list of them) that approach the controversy from different points of view. AE911Truth is an organization of around 1500 architects, structural and civil engineers who have examined the official account and have found that it is simply not credible.
In this 58:13m interview from their Free Fall podcast, the program host interviews two such professionals about two upcoming events their organization is planning for the 15th anniversary of this tragic and mysterious event: the distribution of a booklet to 35,000 structural and civil engineers challenging the official 9/11 story from a physics point of view, and discussion of the upcoming Justice in Focus symposium in New York City to study issues about how to proceed with legal actions. The first topic is introduced by discussing an open letter to Zdeněk Bažant who provided a scientific explanation in support of the official story, but AE911Truth experienced a futile attempt to publish an article in an engineering journal in which they took issue with his explanation.
