I had the pleasure of working with John for a long time (13 yrs). Over those years I heard nothing but positive things about him and believe me, I heard a lot. He always handled himself well and his work ethic was superb. The Air Force Space Command community will have a tough time trying to fill his shoes with just one person, he was the goto person for all things related to the Integrated Tactical Warning Attack Assessment system. Despite his professionalism and superb work ethic he always took the time to simply chat, whether it be about sports, indy racing, a trip he had taken or just ask about your family. He'll be missed by all.
