regarding my earlier comments in this thread about I didn't see a CO2 scrubber on-board....and how that was a stupid and cheapskate mistake.......
- this appears to be confirmed as I read this just now:
As the oxygen level falls, the proportion of carbon dioxide being breathed out by the crew will be rising, with potentially fatal consequences.
"As levels of carbon dioxide build up, then it becomes sedative, it becomes like an anaesthetic gas, and you will go to sleep."
Too much of the gas in a person's bloodstream, known as hypercapnia, can kill them if not treated.
Former Royal Navy submarine captain Ryan Ramsey says he looked at videos online of the inside of Titan and could not see a carbon dioxide removal system, known as scrubbers.
"That for me is the greatest problem of all of them," he says.

So once again, Stockton '
Obscenely Safe' Rush with inadequate & cheap design, failed to install a CO2 scrubber (and they're cheap) in the submersible. cheap cheap cheap, poor design, poor build, lack of 3rd party testing, lack of 50-yr-old experts, cutting costs all the way, and it's just a shame he took 4 others with him to their watery graves.
Current score:
Titanic: 1,517 + 5.
Mankind : 0
