An explosion on an offshore oilrig off the coast of Louisiana has left seven workers badly injured and 11 missing. An Associated Press story on the disaster mentions that two of the injured workers have been transported to Mobile trauma center for care.

Seven workers were reported critically injured, Coast Guard Lt. Sue Kerver said. Two were taken to a trauma center in Mobile, Ala., where there is a burn unit, but the nature of their injuries was unclear, she said. At least two were taken to a suburban New Orleans hospital.
