‘I’ve broken some rules’: OceanGate boss revealed window on Titanic sub would get ‘squeezed’ under pressureBut in an interview last year, Mr Rush said that OceanGate had worked with all three institutions to develop the pressure vessel for the Titan."The pressure vessel is not MacGyver at all, because that's where we worked with Boeing and NASA and the University of Washington.
Mr Rush admitted in an earlier conversation that he had broken rules with the materials used to build the Titan's hull. A clip emerged where Mr Rush told Mexican actor Alan Estrada about the sub’s seven-inch thick acrylic window - the only way to gaze out onto the wreck of the Titanic.He said the window gets "squeezed" as the craft gets down to 12,500 feet below the surface.
"It is seven inches thick and weighs about 80lbs. When we go to the Titanic it will squeeze in about three-quarters of an inch and just deforms.Acrylic is great because before it cracks or fails it starts to crackle so you get a huge warning if it’s about to fail." "There’s picking the rules that you break that are the rules that will add value to others and add value to society, and that really to me is about innovation."It comes as it emerged that the US Navy detected the Titan's implosion days before the ship was found.
