re: Keith Cowing has the right to change his mind!
I think he has changed his mind about, Tumlinson. But it doesn't matter. Cowing has the right to have an opinion on a press release and express it at NASAWatch.com. After all unlike EP he has someplace of his own to voice his opinion. I'm betting he gets paid for SpaceRef.com Reports from Devon Island. In some sense of the word.
BTW in reference to EP's post...I doubt Cowing is wearing a Dewey Analog Spacesuit (canvas) up there, but he could be wearing a Hamilton Sundstrand/Global Effects suit (dacron).
