What else could go wrong?
Hurricanes. The Atlantic hurricane season starts this week, and a big storm would at least temporarily derail relief efforts.
So, what if the relief wells fail?
If BP drillers just miss the main well, they can try again. In an undersea gusher off Australia last year, it took five attempts to connect with the main well, 10 weeks after the spill erupted. In this spill, “the worst-case scenario is Christmas time,” says energy analyst Dan Pickering. “This process is teaching us to be skeptical of deadlines.” At the current rate, 4 million barrels would spill into the Gulf by New Year's Day.
