Five workers in critical condition after oil rig explosion in La.
Seven workers were injured last night – five of them critically -- when an oil rig exploded on Lake Pontchartrain, Louisiana. News sources say the Coast Guard is searching for one person who is still missing. All of the workers suffered blast-type injuries and burns.
The cause of the blast has not yet been determined. Also unknown: whether or not the incident spilled oil into the lake, a 630 square mile body of water located in parts of six different Louisiana counties.
