June 23, 2006: C-3 says bye bye and take the plunge

Jonathon is on holiday - so improved video next week

Video Segments
Sparky does it again - and welcome back to Sharon and her water taxi service. Somehow my last visit without Sharon's smile was incomplete. Sharon, Kim and the others have become an essential part of our team

Sparky and his smile

12:56:38 - Before with the Copco resting on C-4 - drilling for the next foundation blast

The ignition sequence from video frames

T = 0.267 sec      T = 0.300 sec

T = 0.333 sec      T = 0.367 sec
(Note the 0.3 sec delay between ignition and detonation - seen at the bottom of the pier columns)

T = 0.400 sec      T = 0.433 sec

12:57:34 - And the Copco silently watching over Mickey, Ken and their team

And only the foundation remains - with the John Henry drilling on the old Grace support in the background.
