Next Best Option on Gulf Spill "Junk Shot"?

After what appears to be a failure of the "dome" to harness the Gulf oil leak, is this what's being planned?

Suttles said that another possible solution would be to "take ground-up material of various types and try to inject it into the blowout preventer at the bottom of it and it will flow up and plug it up," an operation he compared to stopping up a toilet.

The maneuver is called a "junk shot," Suttles said.

The blowout preventer is a 48-foot-tall, 450-ton apparatus that sits atop the well 5,000 feet underwater. It would stop the leak, BP has said, but it has not been working properly since the Deepwater Horizon oil rig exploded in flames on April 20 and sank two days later, triggering an oil spill that President Obama has called a "potentially unprecedented environmental disaster."
