The reality is that there has never been anything more than random information thrown out by CTs claiming that the house of cards is evidence. There is no proof, only observations which are completely incorrect, "evidence" that has been refuted, and unanswered questions (an unanswered question is not evidence, it's simply a question that hasn't been answered yet).
If anyone wants to really challenge their belief in the 9/11 conspiracy theories, go here:
