Thanks, MatrixElement, for the look-see underground.
I was in my office working Sunday when they were filming. Several police cars arrive on the scene right in front of the corner and cops jump out, scramble around, etc. I didn't see any "jumper". The cranes were really interesting to see in operation - they had two water tankers connected to each crane and a LOT of water was being pumped out as artificial rain. For some reason, BA looks better in the rain. Those trees in the planters help as well - I thought they were to stay for good when I first saw them! The original renders called for trees along Adeliade in front of the building - it would be nice to see those materialize.
