A British billionaire who is feared to be on board the missing Titanic tourist submarinewrote a last post warning about temperamental weather conditions ahead of the mission.

Billionaire Hamish Harding, who has previously travelled on the Challenger Deep to the bottom of the ocean and on Jeff Bezos’ Blue Origin into space, posted on Instagram on Sunday to announce he was joining OceanGate Expeditions for their Titanic mission. That was the last time he posted before news broke that the submersible is missing somewhere in the Atlantic Ocean. In his eerie last post before the mission, Mr Harding said it would be “the first and only manned mission to the Titanic in 2023”. The father-of-two has not been heard from since.
