I’m flabbergasted that someone would equate the risk of getting out of bed with the risk of going 2 and a half miles down in the ocean!!!
Literally gobsmacked!!!😮😮

Very thoroughly and thoughtfully presented. I really appreciate this style of journalism. Not sensationalized and presented in a way that helps you understand clearly. Thank you Andrew!!

The essential failure point here was the mind of the company owner. Every event thereafter was just part of a long causal chain.

Mr. Chang, you are the right person to give these updates. You blend matter-of-fact style with discreetly evident care. Thanks from a fellow Canadian.

Great video. There are NO remains. Physics do not cheat or lie. The five were instantly turned into slightly cooked soup, eaten by fish, crabs and bacteria. The best we can hope for is they recover a few big pieces of the carbon fiber reinforced composite hull along with the two titanium ends, and determine what failed first. As a mechanical engineer, it is easy to see the carbon fiber hull and method of joining it to the two titanium ends was a catastrophe waiting to happen. It was going to fail as soon as 2 or 3 compression cycles (ocean surface to deep submergence and back to ocean surface), up to at most 10 to 15. It was that stunningly bad of a design. It is the height of hubris that Stockton Rush and Oceangate management thought this would work...

I worked for a short time, in occupational health and safety and I can't tell you how many times I was confronted with exactly the same attitude as that CEO guy. That is, in no small part, why I only worked in that field for a short time. Total, utter exasperation trying to get through to people.

If people only knew how many catastrophes could happen but don't every

Wow! Thank you so much, Mr Chang, for explaining this so clearly! Thank you also for the humanity you show to all those grieving the losses of the passengers. 🙏🏻

There are homeless vets going hungry and living under bridges as we speak....WHO is going to mount a "rescue operation" for those people? This disgusting income inequality is going to blow up in our faces one day.

They want a Titanic experience and Stockton Rush's arrogance not kidding to provide a real Titanic experience including himself. RIP. Titan is a submersible coffin with a Logitech Joystick. Titanic is a gravesite, not a tourist attraction, and should be left alone in due respect to those passengers who died tragically.

Well presented.

The thing that concerned me most about the search was that, initially, the focus appeared to be totally on the oxygen window and the evidence regarding the sound of the implosion having been heard seemed to be withheld (for fear that the search and rescue effort would not take place, I wonder?). Searchers really need to know all these facts so that they can probably balance the risks to the searchers against the likelihood of finding the subjects alive. With such a narrow window being stressed so much to the public, it seems likely that at least some of the searchers would be inclined to put themselves more at risk and the search itself would be more "chaotic" and "panicked" than would have if they were aware of the sound that was heard at the precise time the submersible went missing. Of course, it is possible that this detail was only withheld from the public, but made available to anyone engaged in the search. I hope that is so.

Yes, the searchers would still "answer the call" regardless of how people get themselves into difficulty because it's what they do. I cannot thank them enough for that. They are truly the heroes worldwide.

Excellent level-headed reporting. Very refreshing!

[acoustic]

Rush was incredibly arrogant, egotistical and even delusional to believe it was safe.

[willbelasco]

Thank you, Andrew! This was exactly the type of video update and format I was looking for!

[MrGeoC]

Thank you CBC for creating this series. Excellent journalism.

Andrew Chang rocks! ✊
My understanding is that we do have those laws and certification in place in the US, what this CEO did was to go around them by launching his vessel from Canada instead, and also because he was going to be immersed in international waters, none of those laws applied. There are no laws that apply worldwide.

[zellanutellaa]

I just find it annoying for people to keep asking “will they find remains” like common sense the answer is a hard no.

[Wilson-un]

You want to take a risk and break rules that's fine. Just don't bring others down with you

[rebeccanewland]

Thanks-I needed that! I still am too emotionally affected by this tragedy to think clearly about the facts. So we might never know the truth.

[nibblesd.biscuits]

There's some high frequency buzzing coming from Andrew's mic. Just a note for the production team.

The crew heard the hull begin to fail. They dropped their ballast weights and tried to ascend when the hull failed.
