Gas bubble triggered oil rig blast: report
The deadly blowout of an oil rig in the Gulf of Mexico was triggered by a bubble of methane gas that escaped from the well and shot up the drill column, according to interviews with rig workers conducted during BP's internal investigation.
The bubble expanded quickly as it burst through several seals and barriers before exploding, according to workers.
While the cause of the explosion is still under investigation, the sequence of events described in the interviews provides the most detailed account of the April 20 blast that killed 11 workers and touched off the underwater gusher that has poured more than three million gallons of crude into the Gulf.
Portions of the interviews, two written and one taped, were described in detail to an Associated Press reporter by Robert Bea, a University of California Berkeley engineering professor who serves on a National Academy of Engineering panel on oil pipeline safety and worked for BP PLC as a risk assessment consultant during the 1990s. He received them from industry friends seeking his expert opinion.
Seven BP executives were on board the Deepwater Horizon rig celebrating the project's safety record, according to the transcripts. Meanwhile, far below, the rig was being converted from an exploration well to a production well.

George Noory + Steve Qualye + Richard C. Hoaglund = tremendous amount of BS, Lies, Deception.
I visited Richard C's facebook once and all I saw was his claims that CIA had infiltrated his fanpage.
Please stop inundating ATS with BS. Please.

With the emerging evidence of fissures, the quiet fear now is the methane bubble rupturing the seabed and exploding into the Gulf waters. If the bubble escapes, every ship, drilling rig and structure within the region of the bubble will instantaneously sink. All the workers, engineers, Coast Guard personnel and marine biologists measuring the oil plumes' advance will instantly perish.
As horrible as that is, what would follow is an event so potentially horrific that it equals in its fury the Indonesian tsunami that killed more than 600,000, or the destruction of Pompeii by Mt. Vesuvius.
The ultimate Gulf disaster, however, would make even those historical horrors pale by comparison. If the huge methane bubble breaches the seabed, it will erupt with an explosive fury similar to that experienced during the eruption of Mt. Saint Helens in the Pacific Northwest. A gas gusher will surge upwards through miles of ancient sedimentary rock—layer after layer—past the oil reservoir. It will explode upwards propelled by 50 tons psi, burst through the cracks and fissures of the compromised sea floor, and rupture miles of ocean bottom with one titanic explosion.
The burgeoning toxic gas cloud will surface, killing everything it touches, and set off a supersonic tsunami with the wave traveling somewhere between 400 to 600 miles per hour.
While the entire Gulf coastline is vulnerable, the state most exposed to the fury of a supersonic wave towering 100 feet or more is Florida. The Sunshine State only averages about 6 inches above sea level. A supersonic tsunami would literally sweep away everything from Miami to the panhandle in a matter of minutes. Loss of human life would be virtually instantaneous and measured in the millions. Of course the states of Texas, Louisiana, Mississippi, Alabama and southern region of Georgia—a state with no Gulf coastline—would also experience tens of thousands, if not hundreds of thousands of casualties.

Just to clarify...Are you getting this information from your FaceBook again? Pretty sure you know where I'm going with this.
