On lack of Air Defense on 9/11:

"Here is a short video by the German freelance journalist and author Paul Schreyer, based on his new book Inside 9/11, which "contains a short summary of the publicly available--but still widely unnoticed--evidence for a supposed attempt to obstruct the air defense on September 11th, 2001." The video focuses in particular on the actions of Colonel Robert Marr, the battle commander at NEADS on September 11, 2001."
