Ms Shotwell would probably be a very good person to manage NASA, but it will never happen. As “First Buddy”, Musk would likely never allow his best people to lured away from SpaceX. Personally, my opinion is that Mr. Isaacman is one of the better nominees the administration has proposed so far. Both NASA and the FAA are hidebound agencies that have been roundly criticized for being mired in bureaucracy and actually inhibiting progress instead of enhancing it. If he brings a fresh approach to the position and does a thorough analysis, he might actually make some significant progress.
