Keith's note: I just learned that John Cox passed away last night after a lengthy illness. I got to know John very well when I worked for him at the Space Station Freedom Program Office in Reston (Level II). Those of you who also worked there will recall that it was a place where people often expressed their opinions with little restraint - and it got to be rather boisterous at times. In contrast, John always seemed to be one of the calmest people in the room.
John had quite an unusual background for someone who rose through the ranks at Mission Control (where he was known as "Granite Flight") - his doctorate was in biomedical engineering. As such, he always seemed to have a slightly different angle on things than the typical NASA manager - and he did not need a bunch of acronyms to express that view.
