June 5, 2006: Blowing the P-12 substructure

It all started very simply - I was enjoying my morning. Then Sparky phoned and said that Mickey's team would blow P-12 at 3pm. I was hooked. There are many photos and a good story - but here is the start.

On the way out - some familiar landmarks and friends: Cousin Arthur

Michael and his 1250 and P-something

On the barge - Manny, Jackie and Leon, fishing for Pearman segments

and a better view of Leon (playing the grapple) and Jackie (playing the shear)

And the team

James Whitten

Ken, Mickey and James (of the O'Dell clan)

All purpose Lewis

and a surprise from Sparky - Mickey and myself, with Ken in the background checking the transmitter.

Before

Ignition (from Mickey's camera - what timing!)

and sequential still photos. About 2/sec. See below for the ignition sequence from the video frames.
