Yeah of course. DSLR and macro lens. Costs about 5 times as much as the pixel which makes excellent landscape and portrait images but it sucks at macro.

>what happened?
culture of optimism
disregard for safety
muh innovation

I'm no engineer but Stockton Rush clearly was a madman who openly said safety is for pussies and hinders innovation. He got what he deserved. I have no sympathy for the tourists either, if you don't do your research before going on such a trip it is likely one-way. The OceanGate company was known for questionable safety and lying about their merits like working with NASA. Never happened. The entire thing was very improvised. That worked for a while but at some point you're simply out of luck. And dead.

Again I'm no expert on this but one does not simply build a submarine from carbon fiber composite material. This stuff is complex, behaves unpredictably and undergoes fatigue with no obvious warning signs until a sudden breaking point is reached. It isn't ductile like metal. Metals like steel are much more predictable and show clear signs of fatigue before they fail catastrophically and these signs are relatively easy to detect. Composites are much more difficult to analyze for defects and basically a black box. You have no idea what's going on deep inside that material regarding delamination a d cracks of the epoxy matrix. There's a reason most submarines are still made of metal. Because it works. But that wasn't cool enough for this guy.

So if you ask me, what happened is the sub imploded from microscopic fatigue accumulated over time, likely at the contact zone between the carbon fiber tube and the titanium end caps / porthole window which was blown out. Put the screw-on cap loosely on a toothpaste tube and step on it. Pretty much this. Rush said himself he knew the Titan suffered from fatigue but employees pointing out this was potentially dangerous were fired.

To me the real question is - why was this company even allowed to commercially operate this sub with tourists on board though it wasn't certified for it? People always make fun of us Germans for overregulation and Deutsche Industrienorm but something like this could never have happened here. Your craft is not certified for the commercial application you intend to use it for - you cant use it. And there are over 9000 regulations involving every component making sure you don't do stupid shit like this company. They claimed the Titan wasn't classed because it was an 'experimental vessel' and classsing is bs anyway. Well you can't take tourists on an experimental vessel for money, it's that easy.
I’ve read this was only possible because the operation took place in international waters lol. Let that sink in
