Documentary on missing Titanic submersible to air before oxygen supply runs out

A British broadcaster would air a new documentary focusing on the search to locate and rescue the Titan submersible which went missing on Monday.

UK's Channel 5  is broadcasting "Titanic Sub: Lost at Sea’ Documentary" before the vessel runs out of its four-day oxygen supply on Thursday. 

According Variety, “Titanic Sub: Lost at Sea” has been scheduled to air on Thursday at 7 p.m. local time. 

Produced by  ITN, the documentary promises to “go beyond” news coverage and bring viewers up to date, while examining the wider context about the voyage, its passengers and the fascination with the Titanic shipwreck. The film will also talk to experts and look at the rise of extreme tourism.

Speaking about the documentary, managing director of content for ITN  said: “This program will chart everything from the exploration itself, to the rise of extreme tourism, to the rescue attempts, but above all it will tell a very human story that has captured the nation which is about 5 people, all with families, who are trapped at the bottom of the ocean. Our expertise and heritage in fast-turnaround documentaries and reputation for responsible filmmaking means we always treat such stories with great sensitivity.”

Rescue teams were racing on Wednesday to trace the origin of sounds heard from the depths of the North Atlantic in a search for a tourist submersible with five people on board that vanished on its descent to the century-old wreck of the Titanic.

The U.S. Coast Guard said remotely operated vehicle (ROV) searches were deployed in the area where Canadian aircraft detected the undersea noises using sonar buoys on Tuesday. Estimates suggest the submersible's air supply could run out by Thursday morning.

"We don't know the source of that noise," U.S. Coast Guard Rear Admiral John Mauger told CBS on Wednesday. Two ROVs and a surface vessel are being used to try to locate the source, he said.

"This is an incredibly complex site," Mauger said, noting that metal and other objects under the water made it difficult to determine the source.
