Real stories of people in peril, the Titanic submersible trip to the Thai cave disaster, affirm a collective wish for human ingenuity and spirit to triumph

The discovery of wreckage from the Titan submersible last Thursday on the North Atlantic seabed close to the wreck of the Titanic brought to an end a five-day vigil of hope around the globe. The chances of rescuing the five occupants of the missing sub always appeared slight, but it was perhaps the very unlikeliness of that outcome that increased the appetite to see it realised.

In the era of 24-hour news, few events grab the public imagination quite as firmly as a real-time people-in-peril story. And it’s hard to imagine a more extreme or unpleasant peril than being trapped in deep sea in a craft the size of a minivan, as the oxygen supply runs out, and there is nothing to do but attempt to control your breathing in a situation that screams panic.
