Oil has stopped gushing into the Gulf of Mexico, at least for the moment.
A leaky cap has been replaced and a new one is apparently holding back the flow. Engineers are testing pressure levels under the cap: the hope is that the pressure rises; if it falls, oil might be escaping from somewhere.
Even if the test is successful, the cap is only a temporary measure. Adm. Thad Allen, the head of the federal response to the spill, says that the relief wells that BP has been working on to stop the spill at its source must still be completed to bring a permanent end to the crisis.
Still, this is the best news since the well exploded in April.
