If it was my family member, I'd be relieved it was likely an instant death rather than sitting there aware you were suffocating.

Despite the risks of entering such an inhospitable environment, Rush appears very confident in his invention in the clip, that has emerged on TikTok.
'It’s acrylic – plexiglass,' Rush tells Estrada after being asked what the window mounted at the front of the Titan vessel is made of.
'It is seven inches thick and weighs about 80lbs. And when we go to the Titanic, it will squeeze in about three-quarters of an inch and just deforms,' he explains.
'And acrylic is great because before it cracks or fails, it starts to crackle so you get a huge warning if it’s going to fail.'

I'd like to be remembered as an innovator,' Rush is then seen telling the actor. 'I think it was General (Douglas) MacArthur who said: "You're remembered for the rules you break." And you know, I've broken some rules to make this.
'I think I broke them with logic and good engineering behind me. The carbon fibre and titanium, there's a rule you don't do that – well I did,' the CEO says.
'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.'

I feel so sorry for the families and for the employee who lost his life.
