The frame is complete. No, this isn't a duplicate of Friday's picture. Note the 4' risers all around the bottom, which give the dome its final height of 28' at the center.
Framing was a sometimes arduous process, and the frame would often threaten to wobble itself to bits up until the bottom bracing was put in place. Then, the whole thing became steady as a rock. This is the nature of the dome shape -- it exerts pressure evenly downward and out, so it will pretty much never collapse as long as the foundation ring is uncompromised. Concrete domes have been known to stand for centuries completely unaffected by the passage of time.
