The missing submersible that vanished with five people on board is controlled by a PlayStation controller and has one window for explorers to peer out of.<br /><br />This is based on the Coastguard’s estimation that those on board have 72 hours of oxygen left on board – with the carrier having a ‘life support’ of 96 hours.<br /><br />Titan went missing off the North American coast in the Atlantic and is believed to have one crew member and four other passengers on board.<br /><br />The Boston Coastguard and Canadian Coastguard are both now looking for the missing vessel that is operated by tour company OceanGate Expeditions. <br /><br />The sub, owned and operated by OceanGate Expeditions, was taking a crew of five people - including company CEO Stockton Rush, French explorer PH Nargeolet and Harding - 12,500ft underwater as part of its $250,000-a-head Titanic tour.<br /><br /><br />The crew launched at around 4am on Sunday but lost communication with the mothership just one hour and 45 minutes later. <br /><br />According to OceanGate's website, the sub can last for up to 96 hours underwater with five people consuming oxygen. <br /><br />But more than 30 hours into the rescue mission, it is still nowhere to be found. <br /><br />At a press conference, Rear Admiral John W. Mauger said the US Coast Guard is working 'as hard as possible' to find it while 'lives are at risk'. <br /><br />'We began immediately to mobilize assets to search both the surface of the water, search from the air, and to detect any vessels under the water as well. We've had a comprehensive search to find these people.<br /><br />'We don't have equipment onsite that can do a survey of the bottom... there is a lot of debris [at this wreckage] so locating will be difficult. <br /><br />'We don't have the capabilities at this time. Right now, we're focused on trying to locate it,' he said. <br /><br />Sea conditions in the search area right now are 'fairly normal,' said Mauger, with three to six foot waves, low visibility and fog. . <br /><br />'It's very worrying. It could have become entangled in the wreckage of Titanic, we don't know yet,' said Parry.<br /><br />'The wreck site is a long way from anywhere. The only hope one has is that the mothership will have a standby craft that can investigate immediately what is going on.'
