Everyone has bad days. Some just last longer or happen with greater frequency. If it appears I am having a bad day I generally hope for all the coming terrible news to flood me now. Why screw up another perfectly good day? Then I can put the horrible one behind and move on.
An expert testified that when something goes wrong with a well, the fail-safe device's shears are supposed to clamp down, cut and seal the drill pipe, preventing the oil from escaping.

With a key piece of evidence raised from the depths of the Gulf of Mexico and BP's Macondo well ruled a threat no longer, the focus shifts to what went wrong and who is to blame.Had it functioned properly, the blowout preventer would have sealed off the well after the explosion that ripped through it in April and the biggest maritime oil spill in history would never have happened.
The Gulf oil disaster isn't the only time a blowout preventer failed to stop an explosion. On June 3, a natural gas well in central Pennsylvania erupted despite the fact that it too was outfitted with a blowout preventer, spewing gas 75 feet into the air for 16 hours before it was brought under control.
