Authorities race against time to save Titanic sub

The rescue mission to find a missing tourist submersible, which lost contact on its descent to the Titanic, has expanded deep underwater. There are five people aboard and the US Coast Guard estimates they have about forty hours of oxygen left. Also on the programme: we hear from the 13-year-old Ukrainian author who kept a diary of her journey escaping Russia’s invasion, and the full-time accountant who recorded this season's fastest 100m time in Europe.
