January 17, 2006: Imploding D-23 and the D-25 substructure

While I was in Singapore, Mickey got the action of Ken and the guys with a double barreled day - dropping D-23 (at the edge of Drum Island) and taking the top off of D-25. Here is the before.

Here, D-25 has started

D-23 is resting and the top of D-25 in the background is fractionating

The D-23 ignition sequence is almost complete

and the cap ignites

and starts to fractionate and drop



Its all over but the smoke

D-25 and D-23 after the smoke cleared

D-25 after

Ken with a smile, actually big smile

D-23 after

Testa moves in and starts the cleanup
