Underwater Noises Detected In Search For Missing Titanic Submersible

A Canadian P-3 maritime patrol aircraft detected "underwater noises" in the area where search and rescue crews are looking for the missing Titan submersible that went missing while diving towards the Titanic's wreckage with five people on board. 

"The sounds from underneath the water were heard by sonar devices deployed to find the lost 21-foot submersible. The banging sounds came every 30 minutes when first detected Tuesday and were heard again four hours later," CNN said, quoting the memo. 

According to the US Coast Guard, "Canadian P-3 aircraft detected underwater noises in the search area. As a result, ROV operations were relocated in an attempt to explore the origin of the noises. Those ROV searches have yielded negative results but continue."

In a second tweet, the agency said, "Additionally, the data from the P-3 aircraft has been shared with our US Navy experts for further analysis which will be considered in future search plans."

The search area is the size of Connecticut, about 900 miles off the coast of Cape Cod at a depth of 13,000 feet. 

OceanGate Expeditions operates the vessel that its CEO, Stockton Rush, pilots. The other four men include British aviation businessman Hamish Harding, French diver Paul-Henri Nargeolet, British-Pakistani businessman Shahzada Dawood and his son. 

As of Tuesday afternoon, a Coast Guard official said the vessel had 40 hours of oxygen supply left. As of early Wednesday morning, this would mean the vessel would run out of oxygen around 0600 ET Thursday, according to CBS News. That's if the vessel is still functioning. 

It's a race against time to find the missing sub.
