Closer examination (slower, closer drive-by) reveals in fact the
vertical truss just plain broken.  Looking closely, lots of twisted
metal, and broken sections.

You can now clearly see where several pieces of the steel skeleton
of the new building portion are bent and twisted, where the crane
came down.

All of it is still there, so pictures should be showing up on
the internet.

If a failure report ever becomes available, this will be interesting
to read.
