According to the LA Times, British Petroleum's "top kill" gambit has succeeded in staunching the Deepwater Horizon seabed oil leak.
"U.S. Coast Guard Adm. Thad Allen, the paper said that the “top kill” procedure has blocked oil and gas from the well. Once the pressure has fallen to zero, engineers will pump cement into the hole to “entomb” the well."
Keep your fingers crossed. I'll bet that's what they're doing at BP's head office right about now.
Update - Just checked out BP's live video link. It's down.
