#3 Air "amount" is deceiving. CO2 accumulation will kill you if its partial pressure is high enough against oxygen/nitrogen content.

I wonder if they even have submarine/maritime grade CO2 scrubbers? Or, as some have said, were they just pumping more oxygen in to keep the O2 levels up because it is less weight and cheaper than filtering and scrubbing the air, and betting the short duration meant they didnt need to bother with the expense. Problem is that results in an enriched oxygen atmosphere to stay ahead of the CO2. Oxygen enrichment is problematic if you have a spark.

Plus there was only one hatch. And no way to open the only hatch except for the 17 external bolts that were cinched down tightly to seal the craft shut. Accessible only on the exterior. Essentially they were spam in a can.

Also, apparently there was no high pressure vent system and nor reserves to purge toxic gas or smoke in the case of electric fire.

Does nobody remember history? Any of those young engineers ever heard the names Roger Chaffee, Ed White and Gus Grissom? Apollo 1.

They couldn't purge their sealed capsule, and they burned to death while waiting on the pad engineers to undo the external bolts to open the only hatch to rescue them.

History is quite a harsh teacher to those who refuse to learn from it.

Good thorough research dig.

#6 A Boris-A or Yasen-M class submarine bobbing to the surface in the Atlantic with OceanGate sitting on it's deck and the crew waving from the bridge, would be a real pant leg filler.

#8 OceanGate refused to pay extra for a viewing window that could be safely used at a depth of 4,000 meters.

So basically you could just watch a monitor from the safety of the surface and get the same feedback.

#10 /\ "Watch a monitor"

What? No media coverage? No fotos for home or office 'hurray for me' room? No colorful jacket patches or caps?

But controllers. MSI, or don't go home.

#18 Hull was carbon fiber composite, can you say rapid de-lamination! Also from experience with high power rockets this means confetti!. Composite materials are really strong until they aren't!

#20 I find the story of Maria Strydom, the vegan who died climbing Everest, much more compelling.

She died doing what she loved: lecturing the rest of us about veganism.

#21 The finding of the debris field that may be the remains of the OceanGate gives me hope that it suffered a sudden catastrophic hull failure. At the depth where they were probably at, it would mean an almost instantaneous death, rather than one spread out over days.

#24 Fox reporting the USN picked up sounds of an implosion on day 1.so just who the hell kept up the wild goose chase, spending dollars, burning up equipment and risking only God knows how many lives for what? They were dead on day 1, they were dead on day 5, and are gonna be dead for a long time. Just dumb luck none of the many rescue vehicles crashed or sunk.
Just who ok’ed that circlejerk???

#25 USN, they may have heard an implosion, but not necessarily connected it with the OceanSpace vessel. Or they may not have had an exact location of the implosion.

#26 As I understand it hydrophone returns are never purely linear, and defend on the location of the detecting device with relation to the detected sound.

#28 Re: SOSUS; story indicates sound consistent with location, and SOSUS operators pretty sharp. Read the alternate theory about loss of Thresher, tapes revealed high pressure air system problems, 42 yrs of experience operator tried to disprove rickovers issue. Tapes still classified.

#29 At that depth given the pressure, the wavefront of the implosion would be about 2000m/s. The thing was at most 3m wide, imploding from all sides means it only has to cover 1.5m. That’s less than a millisecond. Blink of an eye takes 300 ms. At least death was pretty much instantaneous.
