Video – Disused gas holder falls to blast…

BGE gas holder implosion goes to plan under watchful eye of CDI.

As the clock ticked down Sunday, the morning clouds disappeared, as if they were in on the months-long planning that went into the destruction of Baltimore Gas and Electric Co.’s final natural-gas holding silo.

Then, as if someone were turning on Christmas lights, the rings of the cylinder blinked with 420 explosive charges.

It took a moment for the noise — like thunder after lightning pierces the sky – for the rat-ta-tat-tat to reach the observers on the roof of Baltimore Polytechnic Institute across the Jones Falls Expressway.And in less than the 7 seconds predicted, the 258-foot-tall hollow steel structure was reduced to a pile of rubble, about 25 feet high.

Precisely at 7:30 a.m., there were puffs of smoke and dust as the copper pins in the explosive charges cut the steel more cleanly — and incredibly faster — than a blowtorch.
