Rescuers are this morning again attempting to access the wreckage of an MH-65C Coast Guard helicopter that went down in Alabama's Mobile Bay last night, having been thwarted by foggy conditions in the search for three missing crew members. Divers overnight failed to gain entry to the wreckage, which rests in about 13 feet of water, reports the AP, but will try again as visibility improves. One crew member has been found and declared dead. (More helicopter stories.)
