Catfish,

First of all - thank you for explaining some of the intricacies of this field to us laymen. Now - from what I have read, they are saying that this is leaning toward the rig hitting a methane pocket and this is what caused the explosion. Can you elaborate on how that would work, since what I read indicated that at that depth methane would actually be in a crystalline structure?

Also, it appears that there were numerous "fail-safes" that subsequently failed - including something called a "deadman". I assume this is like a deadman's brake on a train, just different in what it does?

Any info you care to share would be great - while this is a disaster without question, it is increasing my knowledge of the subject, and I always enjoy that.
