Photos taken today, Friday (May 15). Like ImmenselyMental above, I happened by as one of the sections of the west Rail Climbing System was being taken down. The RCSs installed the skin, and with 9 sections for each of the 3 RCSs to be taken down, 2 more were removed today, leaving 17 of 27 total sections left.
Something new, or at least something I'd not noticed before, but there are now some windows on the crown, at least on the north side, just visible in the second photo on the left side of the box enclosing the tuned mass damper.
