A specialist rescue vessel was this morning powering its way to the trapped Titanic tourists in a last-chance effort to save the five missing submariners after underwater noises were detected overnight.
The Horizon Arctic set sail from St John’s in Newfoundland - from where the expedition left on Saturday - shortly after 12am today.
It was laden with a raft of heavy machinery and submarines that rescue officials believe give the crew of the Titan submersible their greatest chance of being found.
