>>3053398Haven't done any work in CC, but I worked on Year in Space and have been through all of LBJ and on the floor in Kraft during a conference call. NASA is one of the weirdest organizations to work with. Security gave me a pass that allowed me in all but one building, without escort. On the other hand, my boss is Swiss, and had to have a handler with him at all times, to the point where I couldn't drive him on or off property without a NASA PAO in the car with us. Super friendly and accommodating people.
OP, if you haven't seen the images from Dan Winters book Last Launch, go find them all now, its stunning.
