This September 14, 2001 letter from Dr. Anthony T. Kern, a retired United States Air Force Lieutenant Colonel and a former Professor in Aviation Studies and Director of Military History at the USAF Academy, courtesty of the Urban Legends Reference Pages: Rumors of War (Colonel of Truth), provides some great insight into the physical and psychological battles we can look forward to in the future if we actually go forward with this thing.

Here's the introduction a friend of mine received with it: "This was written by my academic advisor at the Academy. He was not only one of the most brilliant men I've ever met, but also an individual who combined that brilliance with common sense to lead others. His words are the ones that haven't been heard yet but I believe will come to be true before we have the chance to recover from this initial tragedy."
