Can I ask as a spearfisherman, why didn't he use a knife to cut the line. He couldnt open those snippers and then he dropped them with precious time and you can tell he really panicked. Why not have a simple dive knife and just cut all the lines needed, seems more simple?
@@CharlyDavis5594 Agreed, most likely Nitrogen narcosis, since Oxygen toxicity and other mixed gases either causes violent convulsion or a simple black out. In any event....pure stupidity all around....sorry! I'm 68 now, back in the 70is, mid 80is I was a silly, bullet proof Idiot of a high risk taking wreck diver, chasing very lucrative loot all over Europe, I'm German.

Dave just did not listen....may he RIP!
RIP to Don and Dave. i don't know how to say it but, how significant is Dave. this might be the 3rd or 4th documentary i watch regarding the same incident.
Things I learned. Do NOT change your equipment before a dive (helmet + camera). Do NOT attempt to recover a corpse at record setting depths. Dead bodies are Buoyant. Practice body recovery in a pool or shallow depths with different scenario complications. Take out life insurance and stay current on premium payments. Do NOT push your pre-set dive limits Do NOT break your own RULES. Do NOT go back for Deon's head.
At that time, there was not as much technology as there is today. I think with today's technology, Deon's head can be found. I wonder about that the most. I cried more for Deon than for Dave. He is almost the same age as me. his family is very sad
If I'm Deon's family, I am telling Dave and his team not to go for the body. It's not worth risking lives for a dead body. If Dave still wanted to go down then I'd tell him not to do it for us or anyone else, only himself.
Family was incredibly respectful, and Dave was going down there regardless, and it simply gave them an objective other than 'going deep.'' That poor family has dealt with needless guilt ever since the tragedy. Don't add more. Not to mention minimizing Dave's astounding success and posthumous recovery of Deon's body let two grieving parents see their son one last time and bring him home. None of that deserves your derision or disrespect. At the time, more people had walked on the moon than did what Dave accomplished. He and all explorers deserve our respect. Deons parents famously said they were proud their son had the most beautiful grave site in the world prior to the dive and they also wept with joy upon bringing their son home. Amateurs second guessing and disrespecting professionals is embarassing.
@@josephmatthews7698I see no disrespect from his comment at all, simply saying how he would have went about the situation if it was him in those shoes. Ppl are different it’s ok bud….
to be completely transparent . Dave havent done this entirely as a favor to the parents. He did it for his ego also and the dead body was an excuse. i think that it was very likely even bigger reason than the favor.
I recently heard that a lot of cave divers actually have death wishes. Same with the people that crawl into tiny spaces. The fear response mechanism is so deeply into DNA that you would need to be a true psychopath like Alex Honnold for example, who doesn’t have any fear response.
I watched the whole video and it is very sad and moving. But the artistic way they tried to tell the story, I am still confused about what happened. Maybe because I am not a diver so I dont get a lot of the jargon or technical side of diving. People go back for a body, the man that gets to the body gets sick and dies. But both bodies are tied up in the rope and the team hauls the ropes up and both bodies are there? If that is correct, how sad and horrifying.
EM-Waves are absorbed by Water. You could transmitInformation via a Tether, which would mean you need 300m of Cable with you. Another Option would be mixing/upconvert your Informationsignal with a Ultrasonic Pumpsignal, and appropriate Downmixing and Filtering at the Top. But how does one Speak underwater with a Breather in your mouth? I guess you could morse, but doing that also requires quite good proficancy in this Skill.
This doc is a masterclass in how to take an absolutely enthralling subject and make it a drawn out, self indulgent, impossible to sit through mess. Literal minute long landscape shots and scenes of people just walking aimlessly with generic ambient music to sounds contemplative. More concerned about showing everyone they went to art school instead of telling a coherent, let alone compelling story. Nothing but self masturbatory tripe. I legitimately had to set playback speed to 2x to even get through it and the pacing was still absolutely brutal.
I’m an enthusiast diver who loves long form stories and films, but I totally agree. I can happily sit through a 5hr podcast, but I found myself constantly hitting the 30s fast forward button. It’s so drawn out, clearly to try to add weight and tension. Unfortunately it does the opposite, as so much is just “dead air” which does nothing to move the story along or add depth (no pun intended). The story is interesting enough, it didn’t need all this fluff added to make it watchable.
I liked it a lot. It's a contemplative, subjective and very personal story, not a by-the-rules-documentary. And anyways, there are a lot of forms which a documentary can take. There is not ONE recipe how to shoot, edit and present a documentary. This is a rather poetic and slow paced one. I was completely comfortable with that, because I watched most of the other footage (news coverage or other documentary-like shorts)about this tragedy and didn't need extra information from this production. For me it was very well made and thought-provoking.
Not exactly. At these depths even the slightest exertion can have lethal consequences. Nitrogen built up in his blood stream effectively making him drunk and the body came loose spinning free at the bottom of the cave making bagging it far harder. Dave's drunken brain hyper focused on bagging the half skeletized and half corpse soap body and spent too much time. When he finally tried to return his loose floating light got tangled and getting it loose was the final straw. He died of poisoning blacking out. This is all from my memory from the incredible outdoors article written shortly after the accident. Now I'm gonna watch the documentary and I invite you to join me to see how accurate I was.
Keep in mind, at these depths he can't just surface. Doing so is instant death. He would have to spend 12+ hours ascending to the surface or risk dying. Trying to do that in a cave without your light might as well be a death sentence so simply leaving it was never an option. (Again all from memory.)
That was don’s equipment that cracked that was on his wrist. He was the one that had the twirlies and the decompression sickness. Dave who passed away had a few problems. He was a the deceased person body when his problems started. There was still buoyancy in Deon (the one they were recovering) with his suit and his line got tangled with Dave’s then he couldn’t get it cut or his own by taking it over his head due to not enough reach from the extra equipment on his head with the helmet and camera mounted on it. then over exertion and panic created too much expended co2. Hope this helped. I had to rewatch. Don talked about how he had no strength to breath after his spins so I imagine kind of the same happened to Dave but quicker cause of the over exertion and panic.
People can do stupid stuff to make world record in disguise of helping someone. He abused his skill to achieve world record instead of helping alive humans. What a waste of talent.
Nuno Gomez. He did his dive in 1994. Deon Dryer died while doing a test dive for Nuno Gomez's dive. Deon had gotten asked to assist in the test dive, and they believe he suffered from a deep water blackout. Dave did his record breaking dive at the end of 2004, and that's when he saw Deon's body at the bottom of the cave. 3 months later is when they did the recovery dive.
I lost my brother cave diving in 1973. Second recorded death in the state of Florida for cave diving. They looked for five days and couldn’t find his body. My dad stopped them from looking essentially told them we’ve had enough deaths. We need to stop now. Later he said he wish you told him to stop earlier. Thank God nobody else died. Three of the six people on that rescue team all died of cave diving the subsequent years.
Why didn't he just take the cam or the helmet off? They must be trained not panic, how to handle line issues. Just as much they know about decompression. I don't understand why this happened to a professional.
There sure is a lot of judging going on in the comments. I feel bad for the people that have never had a mission, or a cause so worthy that yes there could be loss of life. Separating the men from the boys if you ask me and that's part of life. If you want to sit around and watch paint dry then so be it, but don't talk bad about a man that lost his life. Most of the comments will live a life of desperation and loneliness. And say whatever you want, I'm not a diver but every body deserves a proper burial. Live with purpose and God's speed Dave
I doubt that Dave’s family shares your holier than thou opinion of losing a life for no reason. Having lost a child I can promise you that my daughter would be no less dead in a plot at the cemetery than in a cave. Divers that chose to risk their life in some heroic effort that serves no purpose are more foolish than the one they’re trying to recover.
@ajc 1st thing that struck me was why.,, not going back that makes sense but the initial dive. I’m a diver and that amount of decompression for what? Can explore w camera lowered. 10 hrs Is 1 thing … 5 people required to dress u, undress, tuck you in, stay focused on you for 12+ hours not including the amount of time spent planning then praising n congratulating … Thats why the comments., Added layer for anyone that’s ego doesn’t lead… diving is not a skill.., if u r chill n perform under pressure then its as much of a skill as snorkling., 25:50 he just said it .. anyone can dive .. its the decompression again thats ridiculous you hold a rope n stop n go n wait .,,, unclog ears go wait, completely bouyant whole time. Managing the bubbles oh plz.. do we manage our bodies production of gas . After body produces it we control it after but not the production of it. 😬this unfortunately is getting cringy .. hope talk bout guy they r recovering
280m. Thats 29 bar. A safe to calculate SCR is 20 liters per minute at 1 bar. He nost likely has less, but you can't put that in your plannings and still consider it safe. So: That equals to almost 600 liters per minute. A standard 11.1 Liter bottle with 200 bar, fits 2200 liters. Lets assume he has a 300 bar big heavy steel tank with 18l. Thats 4500 liters. That gas tank wouldn't even last 10 minutes. Not even considering that breathing would start to literally suck near 50 bars.
@@conandoyle1740 I appreciate you telling me that. I found this story to be very moving and ended up watching it twice so I could understand the best I could. It’s hard to know what to say to something like this. My dad was in a horrific high speed accident so his casket was closed. It’s a strange feeling to know someone is gone but never getting to see their body.
@@impulse_xs I was having a heard time seeing anything in that portion even after watching it a few times. I’m not disputing that it wasn’t there or was lost in the trying to retrieve the body. After being his resting place for a decade and the head not being part of the wet suit it definitely seems plausible all things considered.
I’ll never understand why they assumed that Dion’s remains would have zero buoyancy. If you have even the vaguest idea what happens to a decomposing body in water, you’d at least think there’s a chance it would float… it doesn’t seem like they actually spent much time thinking about the logistics of handling and moving the physical remains.
Past 100 ft you dont have buoyancy, you sink, b.c. is what keeps us neutrally buoyant when we dive, water is heavy, we gain an 1 atmosphere for every 33ft or 10meters
I did not understand. If he had not panicked his co2 level would not have rised? If he calmed down a little, would it be then ok with oxygen? You just die when you become scared? So hope you don't see a shark!
Looks like a narcissist’s vanity project to me. Surely more than hundreds of thousands of dollars, a lot of people’s lives at risk, to retrieve a cadaver? Don’t tell me it was for thr deceased’s family. He wanted to do something spectacular to be famous (see the whole process meticulously filmed) and died for it.
It was an "excuse to go diving", one of the diver said it on the film. Also, who doesn't want a bit of recognition for their art? What's wrong with it?
I think the distinction between “wanting to do another dive” and “retrieving the body” is rather meaningless here. Something altruistic can be done while coinciding with someone’s other goals. I’d imagine Dave would’ve returned and dove that cave again regardless of Dion’s body. He undoubtedly took an extra risk though and wasn’t prepared to properly handle the body. I’m amazed he thought the body would have zero buoyancy. Seems as if the focused so much on the logistics of the cave dive that they didn’t put nearly enough thought into the logistics of moving the physical remains.
This ain't accident, this is homicide by a already dead person. Why is he spinning, why his torch? Was he waiting for someone to come down to him? Was he alone and wanted companion? Was the cave cursed? How did this happen to a professional diver? Just because you are tangled? Why did they don't dive down immediately? Maybe he's in an air pocket? Was is that hard? Why is there no backup? I am so sooo sorry.
He was at nearly 900 ft and was over exerting himself. That depth is incredibly dangerous just to be there, let alone doing hard work. He passed out from narcosis, and dropped his regulator. It was an accident, one that didn’t need to happen, but an accident nonetheless. His team can’t dive straight down, again too dangerous. For every minute down there, you need to decompress for 60.
Don Shirley, David Shaw's friend and support diver tried to save him, but a part of his equipment malfunctioned and he wasn't able to dive down to him. He couldn't have saved David Shaw anyway, because he was already deceased or in a very critical condition. The cave wasn't cursed and the tragedy is a culmination of different factors, which led to an inescapable situation. Dave Shaw knew the risks and he wanted to do this mission. Everybody knew how dangerous it was. They planned it meticulously, but there are situations you can't plan for.
Cry more. The original was free to watch for years until YT or the owners decided to put it behind a paywall. Besides the directing and editing of this doc is absolutely beyond brutal. Barely worth your time, let alone paying real money for.
@@impulse_xs it's edited like that in the RUclips video so if doesn't get taken down. It's actually 10 times better than this and makes sense when you pay for it.... giving the creators money. I Support art that i like.
@@TheBman57 I’ve seen the original in full and it was just as much of a slog to get through as this. This doc was frankly directed and edited very poorly imo. Pacing was absolutely brutal. The film could legitimately be 10-15 mins shorter if they took out all of the pointlessly long landscape scenes and long shots of nothing important backed by vague ambient music. It was made like it’s some indie film instead of a serious doc. Felt like they were more concerned with showing everyone they went to art school than focusing on a naturally compelling story.
Wouldn't you be arrogant if you mastered your art? On the way, you 'get' to do something good even if it's not your main goal. I think that's great, sad about how it turned out.
@@kevininforks You made no sense. Dave's arrogance is irrelevant to a commenter's accomplishments. Btw, what great thing have *you done? Apparently, your definition of great is risking your life to save 10-year-old bones. That's called stupidity and ***arrogance.

Things I learned. Do NOT change your equipment before a dive (helmet + camera). Do NOT attempt to recover a corpse at record setting depths. Dead bodies are Buoyant. Practice body recovery in a pool or shallow depths with different scenario complications. Take out life insurance and stay current on premium payments. Do NOT push your pre-set dive limits Do NOT break your own RULES. Do NOT go back for Deon's head.
His head is missing?
DONT DIVE
At that time, there was not as much technology as there is today. I think with today's technology, Deon's head can be found. I wonder about that the most. I cried more for Deon than for Dave. He is almost the same age as me. his family is very sad
Oh my, what a moving documentary.

All it took was a little bit of panic. Then it was all over for Dave. RIP.

It was almost certainly nitrogen narcosis affecting him rather than panic.

@@twe6969 So why did Dion’s corpse in the wetsuit begin floating once it was nudged loose and tangle up the lines?
THIS!

I SAID HE IS A REAL HERO !!!
How come the submarine wasnt able to find deon but dave was??
Who's here after watching *the rescue of the kids stuck in a cave*
I did not understand. If he had not panicked his co2 level would not have rised? If he calmed down a little, would it be then ok with oxygen? You just die when you become scared? So hope you don't see a shark!

Looks like a narcissist’s vanity project to me. Surely more than hundreds of thousands of dollars, a lot of people’s lives at risk, to retrieve a cadaver? Don’t tell me it was for thr deceased’s family. He wanted to do something spectacular to be famous (see the whole process meticulously filmed) and died for it.
No i dont think it was for fame but more like a passion driven and justfied by an excuse of retreving a body
It was an "excuse to go diving", one of the diver said it on the film. Also, who doesn't want a bit of recognition for their art? What's wrong with it?
@@Larpushka exactly they said it them selfes 👍🏻
I think the distinction between “wanting to do another dive” and “retrieving the body” is rather meaningless here. Something altruistic can be done while coinciding with someone’s other goals. I’d imagine Dave would’ve returned and dove that cave again regardless of Dion’s body.
He undoubtedly took an extra risk though and wasn’t prepared to properly handle the body. I’m amazed he thought the body would have zero buoyancy. Seems as if the focused so much on the logistics of the cave dive that they didn’t put nearly enough thought into the logistics of moving the physical remains.
This ain't accident, this is homicide by a already dead person. Why is he spinning, why his torch? Was he waiting for someone to come down to him? Was he alone and wanted companion? Was the cave cursed? How did this happen to a professional diver? Just because you are tangled? Why did they don't dive down immediately? Maybe he's in an air pocket? Was is that hard? Why is there no backup? I am so sooo sorry.
He was at nearly 900 ft and was over exerting himself. That depth is incredibly dangerous just to be there, let alone doing hard work. He passed out from narcosis, and dropped his regulator. It was an accident, one that didn’t need to happen, but an accident nonetheless. His team can’t dive straight down, again too dangerous. For every minute down there, you need to decompress for 60.
Don Shirley, David Shaw's friend and support diver tried to save him, but a part of his equipment malfunctioned and he wasn't able to dive down to him. He couldn't have saved David Shaw anyway, because he was already deceased or in a very critical condition. The cave wasn't cursed and the tragedy is a culmination of different factors, which led to an inescapable situation. Dave Shaw knew the risks and he wanted to do this mission. Everybody knew how dangerous it was. They planned it meticulously, but there are situations you can't plan for.
Most lifes problems arise from people wanting to be important..
Play stupid games; win stupid prizes unfortunately.
Definition of foolish
Great story. Horrible music.
Looks like people doing exactly what they should be doing
I hate the title. “DAVE’S” OR “DAVE IS NOT” “DAVE WILL NOT/WILL NOT BE” UGH
The title comes from words written on a slate by Don to relay to the other divers on the team.
Don dies ?
No. Don is currently still alive

You don't own this
get over it…
Cry more. The original was free to watch for years until YT or the owners decided to put it behind a paywall. Besides the directing and editing of this doc is absolutely beyond brutal. Barely worth your time, let alone paying real money for.
@@impulse_xs it's edited like that in the RUclips video so if doesn't get taken down. It's actually 10 times better than this and makes sense when you pay for it.... giving the creators money. I Support art that i like.
@@TheBman57 I’ve seen the original in full and it was just as much of a slog to get through as this. This doc was frankly directed and edited very poorly imo. Pacing was absolutely brutal. The film could legitimately be 10-15 mins shorter if they took out all of the pointlessly long landscape scenes and long shots of nothing important backed by vague ambient music. It was made like it’s some indie film instead of a serious doc. Felt like they were more concerned with showing everyone they went to art school than focusing on a naturally compelling story.
He didn't go down there to help a family say goodbye. He was arrogant and tried to do it because he thought he "could"
Wouldn't you be arrogant if you mastered your art? On the way, you 'get' to do something good even if it's not your main goal. I think that's great, sad about how it turned out.
You've never done anything g great in your life have you?
I don’t think he was arrogant. I think he was confident
@@Larpushka No. Mastery and arrogance aren't the same thing.
@@kevininforks You made no sense. Dave's arrogance is irrelevant to a commenter's accomplishments. Btw, what great thing have *you done? Apparently, your definition of great is risking your life to save 10-year-old bones. That's called stupidity and ***arrogance.
