Sparky and Mickey Rogers came to the rescue while I was at NIH
Here is the before image. Look carefully at the support with the
vertical column of holes - that contains the explosive charge

and from a different vantage point (before)
The blast (from Mickey who works for Advanced Blasting Services).
Note that the blast started at the bottom of the columns and was timed
to work its way up the column.

and from Sparky
The smoke
more smoke
more smoke
and as the smoke settles -
and now - just another cloud
After the blast - just pieces
Another view - and my assessment is that the blasting guys represent another
surgical specialty within the Cashman/Testa team.
And of course - cleanup at the bottom
and cleanup at the top
