Dear Friends: The event known today simply as “9/11” happened in 2001, 17 years ago – some would say so long ago that it is not important today. For the three of us, 9/11 is an ongoing Concern. We use the term “Concern” in the Quaker sense of a spiritual leading that constitutes an imperative to action. None of us has a reputation for irrationality or dogmatism. We have been convinced by a significant body of serious and competent scientists, engineers, architects, and others who form the scientific core of what has become known as the “9/11 Truth Movement,” and we have participated in that movement.
