field close to the wreck of the titanic. for the first time, the bbc has heard from a co founder of the company that owns this sub, asked whether there could have been a catastrophic failure. i can t speculate on what s going on currently, right now. what i do know is, regardless of the sub, when you re operating at depths like 3,800 metres down, the pressure is so great on any sub that if there is a failure, it would be an instantaneous implosion. and so if that s what happened, that s what would have happened four days ago. this video, shot by a mexican youtuber, shows the titan being launched on an earlier dive to the titanic, more than 3,000 metres below sea level. 3,000! the footage, from last year, shows the sub temporarily losing communications.
