With less than 12 hours of oxygen left in the missing sub, rescuers are trying to home in on some “banging sounds.” It’s a good sign the crew is in reasonable shape other than the dwindling life support and lack of radio contact.
Sub search continues
Time is running out for a crew of five brave and wealthy explorers who planned a sub excursion to visit the wreck of the Titanic. Search and rescue teams are attempting something which seems nearly impossible.
It was a huge help that they were able to pick up some “banging sounds.” The challenge now is getting more than one team to pick up the signal. That way they can “triangulate” a target.
One ship catching the sound for long enough can tell which general direction it’s coming from. A second one can draw a line in the direction they hear it from and where it intersects the first line is the spot to look for the missing sub.
This video explains exactly what is going on with the Titanic tourist sub.
They have around 14 hours of oxygen left.

The big problem is that there’s a third dimension involved and they need to also know how deep it’s coming from. That would alter the angle on the other two lines enough to make a huge difference.
Amazingly, it was a Canadian aircraft which “detected intermittent ‘banging’ noises from the vicinity of its last known location.” The search crew “heard banging sounds every 30 minutes on Tuesday and again four hours later on Wednesday after additional sonar devices were deployed.”
That’s a really good sign that the sub crew is alive. The regular pattern is also a clear indication it’s them and not just random noise. Even so, the Coast Guard still can’t pinpoint it.
Focused on the rescue
It’s been confirmed that aboard the Titan sub are the CEO and founder of OceanGate Expeditions, Stockton Rush along with “British billionaire explorer Hamish Harding, renowned French diver Paul-Henri Nargeolet and Pakistani businessman Shahzada Dawood and his 19-year-old son Suleman Dawood.”
Shahzada’s sister, Sabrina, relate that “the Dawood family is solely focused on the rescue of her brother and nephew and hope for their safe return.”
The operator nearly scrubbed the mission due to weather but at the last minute, an opportunity presented and they launched the sub on Sunday morning. It un-tethered from its support ship the Polar Prince without incident and began it’s long descent to the Titanic wreckage which sits at a depth of 12,500ft.

Not quite two hours later, the surface ship lost contact. The operator notes that “titan is equipped with a four-day emergency oxygen supply.”
Nargeolet, has been described as a renowned French explorer and former diver for the French Navy. He was also “part of the first expedition to visit the Titanic wreck in 1987.”
He couldn’t wait to get back down for another look and “was returning on another dive” aboard the now-missing sub.
