Transcript for Search for Missing Oil Rig Workers Continues
Meantime, the search is still on for two oil workers missing after a disastrous explosion and fire that ripped through a gulf oil rig. 11 workers are injured. And abc's john schriffen is in new orleans with the very latest. John, what do we know? Reporter: Well, bianna, good morning. We know that the coast guard launched the chopper just a short while ago to resume the search from the air. All night, they've been out in boats just like this one, using night vision goggles and infrared technology. So far, there's no sign of the two, missing workers. But the coast guard is using the latest technology to find them before it's too late. An all-out effort from the coast guard units from the air and the sea, for the two platform workers who have been missing close to 24 hours. Authorities have not revealed their names or genders. But they believe they are out there alive. The two disappeared after jumping into the water off the coast of louisiana when the oil platform they were working on suddenly exploded. The blast was so intense, black smoke billowed more than 1,000 feet into the air and could be seen 20 miles away on shore. Black elk energy says 1 of 22 contractors onboard, improperly used a blowtorch to cut the pipeline igniting the explosion. 11 workers were medevacked to safety. Four with severe burns. When there's an incident, it hurts. Reporter: As far as the oil spill, the coast guard says the impact is minimal because the rig was shut down at the time. The environmental threat, as we know, there was 20 gallons that potentially were in that 3-inch line, which would equate to approximately 28 gallons of product. Reporter: Not even enough to fill a large suv's gas tank. In comparison, bp's deepwater horizon disaster, 2 1/2 years ago, spilled enough daily to fill the gas tanks of 82,000 SUVs. And just a few hours ago, two more boats actually doubled in size arrived on the scene to help with the search. Which is a 45-mile, by 30-mile radius. The weather has been cooperating. There are no storms in sight. So, they do have a clear line of vision. Hopefully, these two workers will be found soon.
