Signs of life and “banging sounds” have reportedly been detected as rescuers hunt for the missing Titanic submersible.
A Canadian aircraft searching for the Titan craft containing five men, including British billionaire Hamish Harding, is reported to have detected banging every 30 minutes coming from the area where it disappeared.
The banging was noted in internal email updates sent to the US Department of Homeland Security, which Rolling Stone claims to have seen.
Rescuers are in a race against time to find the missing sub, which is believed to have around 30 hours of oxygen remaining.
