This week on 9/11 Free Fall, structural engineer Larry Cooper joins Andy Steele to talk about his days as an activist for Palestinian human rights, when he served as president of the National Unitarian Universalists for Justice in the Middle East, and about his experience since becoming active with Architects & Engineers for 9/11 Truth, where he recently joined the board of directors.

Starting today and continuing over the next month, Architects & Engineers for 9/11 Truth will be releasing an extended interview every Friday with each of the experts featured in our recent documentary film The Unspeakable. Today, we are honored to share an extended interview with architect Bill Brinnier, who lost his best friend, Frank De Martini, on 9/11.
