The submersible, carrying five people on a journey to see the Titanic wreckage in the North Atlantic Ocean, could have less than two days of oxygen remaining. US and Canadian authorities are involved in the search. Meanwhile, a Canadian aircraft searching for it detected intermittent “banging" noises from the vicinity of the last known location of the divers.

As per an e-mail updates sent to Department of Homeland Security leadership, , which was later obtained by Rolling Stone, a Canadian aircraft searching for the missing Titan submersible,  detected intermittent "banging" sounds from the area where the divers disappeared.

“RCC Halifax launched a P8, Poseidon, which has underwater detection capabilities from the air," the DHS e-mails read and adds, “The P8 deployed sonobuoys, which reported a contact in a position close to the distress position. The P8 heard banging sounds in the area every 30 minutes. Four hours later additional sonar was deployed and banging was still heard." 

However, it was not mentioned at what time the banging was heard

The announcement also stated that “the Joint Rescue Coordination Centre is working to find an underwater remote-operated vehicle through partner organizations to possibly assist." Previous reports on the search for the missing submersible have stated that the Navy’s manned rescue craft can only descend about 2,000 feet underwater, and that if the divers were discovered closer to the approximate 13,000 foot depth of the Titanic wreckage, an underwater drone, or remote-operated vehicle, would be necessary to reach them.

The submersible lost contact with its support ship during a dive, with only 96 hours of oxygen available. A DHS official mentioned that, as of 5 hours ago, the Titan had 40 hours of oxygen left.

However, the situation is considered bleak, as no further noises have been heard since yesterday, and the banging is believed to have come from the vessel, Rolling Stone report cited quoting DHS official.
