This is not looking good at all.
There is strong speculation that the BP Spill in the Gulf of Mexico may not be capped at all.
I actually wrote that a couple of days ago, as part of a post on a slightly different topic, after reading a comment on a thread on The Oil Drum, a message board inhabited by oil industry types and at least some well-informed observers.
Now, I see that the same anonymous comment from the same thread has been picked up and quoted by numerous blogs, published in Mother Jones and linked by Huffington Post.
Unfortunately, none of the above have done their homework to further verify the person's hypotheses, other than to say such stuff as it "passes a sniff test", which I could do myself without turning to a national publication, thank you very much.
Anyway, I suppose it may do some good to get this out there and see if it holds up under more scrutiny than some writer's nasal organs can provide.
