(Editor's Note: To many in the know, Dirck T. Hartmann, who worked on the Apollo Space Program and many other significant NASA projects, was a fighter pilot in WWII, flying P38s. So when this gifted scientist/engineer/physicist and 87-year-old hero felt compelled to answer the questions of Man Made Global Warming, not only his son and grandchildren knew he had something to say with factual substance, truth and knowledge. What he has to say is clear and concise and should be read by everyone.)
