[QUOTE=Headhumpy;51605036]The one diving-related accident that has stuck with me over the years is the Byford Dolphin accident. The [url="https://en.wikipedia.org/wiki/Byford_Dolphin"]Wikipedia article[/url] has the details on what happened, but in short, four divers in a decompression chamber were subject to explosive decompression from 9 atm to 1 atm. All died of injuries related to rapid decompression, with one being sucked through a small opening that he was standing next to. He was, using the words of the medical examiners, "completely disintegrated", and his remains were sent for autopsy in 4 plastic bags. The full results of his autopsy are as follows: Later on in the report, the authors noted the following: The other divers didn't fare too great either. All three were found to have large amounts of free fat in the chambers of the heart, as well as the great vessels surrounding it. The fat was mixed with gas bubbles, and "looked like sizzling butter on a frying pan". The authors hypothesised that the boiling of the blood caused lipoproteins to denature and precipitate out as fat. All the organs showed large amounts of gas in the blood vessels, and numerous hemorrhages were found scattered throughout the soft tissues.

[QUOTE=Crimor;51608278]Like "Injury incompatible with life"[/QUOTE] I remember this phrase really sticking out to me during EMT classes. Our instructor told us about a motor vehicle accident he'd responded to where a patient was decapitated and a new medic started CPR on the body anyway, as an example of "injuries incompatible with life".
That's it, never gonna get anywhere near water again. Gonna throw all my swim team commendations I got in high school out and live somewhere miles and miles away from any body of water. Congrats Facepunch, you scared me straight.
[QUOTE=Saxon;51608701]I'm guessing this was the inspiration for this [media]https://www.youtube.com/watch?v=d0s9sG_kWyY[/media][/QUOTE] Unfortunately that wouldn't work, the pressure gradient between 1 atm and vacuum isn't that great. You could probably plug that hole with your buttcheek. You'd get severe bruising but I'm pretty sure you could survive it for a short while. 9 atm to 1 atm is a massive pressure difference, which is why the diver was sucked through the hole and basically shredded. This is a photo of the approximate position of the jammed door: [img]https://i.imgur.com/hCxMxmD.png[/img] And with a person next to it for scale: [img]https://i.imgur.com/X3QtdCp.png[/img] The situation would have been similar to the clip of the crab being sucked through the crack, although not as severe since the hole was wider in this case, and the pressure difference perhaps not as large.

I think what's most unsettling about this video is the almost cheerful way the narrator says "Once it's gotcha, it's gotcha!"
[QUOTE=Crimor;51608278]Like "Injury incompatible with life"[/QUOTE] I remember this term being used for some dude who got stuck in a wood chipper. Can't recall the article but there was images of the aftermath which makes the earlier one look tame.

Pretty sure I saved a close family friends life in their pool one time. When we first got a pool at home I was 8, concrete in-ground with ~2-3m depth at the far end, there was a single drainage port at that end, and dad explained to me why it was dangerous before we had even filled the pool with water. When the pool was full, Dad explained the danger by holding the lid of the filter box closed for 20seconds or so, and then let it go.. I was floating near, but I could feel the water pulling me near it with some strength - he explained that what I had felt was nothing compared to the one on the bottom of the pool. Skip to my family friend at their place when we were ~12, they had jets and shit in their pool, around the same depth, but they didn't have a cover over the drain, and he stupidly got caught in it. So I turned off the jets and the filter box then went back down to help him out (he couldn't move before). It was only me and him swimming out there at the time, we decided to relax and forgo some family get together elsewhere. One of those bizarre things.

I regret going to this thread :vomit: But at least I learned something new
[QUOTE=ElectricSquid;51609363]What the fuck am I seeing? What is that thing? Why does it have skin and a human face and... tits, and why is it feeling up Ripley? :what:[/QUOTE] Welcome to Joss Whedon's interpretation of an Alien film. It doesn't get better.

Why does it have skin and a human face and... tits, and why is it feeling up Ripley? :what:[/QUOTE] It's a half-human xenomorph hybrid. It thinks Ripley is its actual mum. Don't ask why they thought it would be a compelling idea besides symbolism for that movie. [editline]January 1st, 2016[/editline] Just to add to the weirdness factor even more: its original design was to incorporate a mix of both forms of human genitalia explicitly. I wonder what Giger would've thought about it, especially seeing as [URL="https://en.wikipedia.org/wiki/Alien:_Resurrection#Critical_reception"]he liked the film.[/URL]
