An ex-Royal Navy submarine captain has warned the current situation is "bleak" for anyone aboard the missing Titan submersible and the search-and-rescue operation is quickly turning into a salvage mission.
Ryan Ramsey spoke out as oxygen on the vessel was thought to have run out as of this morning.
Mr Ramsey said: "The outlook is bleak, that's the only word for it, as this tragic event unfolds and almost the closing stages of where this changes from rescue to a salvage mission.
