March 12, 2007: Mickey and team: loading the last Grace pier

Today is loading day - Mickey and Ken on the right and Carlos and Michael on the left (I think). Loading consists of placing 1 or more charges with a detonator in the hole, followed by another charge or spacer or stemming. This is tamped into place, the shock tube tail is left hanging to be tied in with the other shock tubes in a predetermined sequence. Sparky got several sequences of loading which I synthesized into short video segments

Only Sparky could catch such an artistic view of the morning work site

The Seabreeze windows are boarded up (again)

I am speculating that Carlos and Michael are loading on the left

while Mickey and Ken are loading on the right. A good example of parallel processing

Here Carlos and Michael are loading

and tamping

Takes two to tamp

Not only are ironworkers acrobats - blasters can also be acrobats
