Not good. Some updates from CNN:
An oil rig has exploded 80 miles off the coast of Louisiana… The accident took place 80 miles off the coast of Louisiana on the Vermilion Oil rig 380, which is owned by Houston-based Mariner Energy.
U.S. Coast Guard Petty Officer Bill Colclough tells CNN that all 13 workers involved in the rig explosion are accounted for, but one person is injured. …
Asked about concerns regarding oil leaks or pollution, Colclough said "there are reports the rig was not actively producing any product, so we don't know if there's any risk of pollution."
More: Ben Armbruster makes a good catch: The day before the explosion, a Mariner Energy official was railing against Obama's temporary moratorium on offshore drilling. “I have been in the oil and gas industry for 40 years, and this administration is trying to break us,” said Barbara Dianne Hagood, senior landman for Mariner Energy.
More: From the AP: "A mile-long oil sheen spread Thursday from an offshore petroleum platform burning in the Gulf of Mexico off Lousiana, west of the site of BP's massive spill."
Aaaaand... Maybe no sheen, after all.
