October 2004An Australian name isDave Shawof amateur divers inBushman Cave, South AfricaWhile diving, I accidentally found oneThe remains of a diver who died 10 years ago.
The remains are located at a depth of 271 meters under the water, and the underwater situation is very complicated, and the difficulty of salvage is extremely difficult.
Dave convened diving enthusiasts to cooperate in salvage, but in the process of salvage, an accident occurred at the bottom of the cave, and the salvage was declared a failure, who knew that 3 days later, Dave actually used"Corpse".Fulfilled their promises.
Dave diving in Bushman.
Dave Shaw was born in Australia in July 1954He showed it from an early ageExtraordinarily smart, in our words, yes"At the age of three, he can read a thousand words, at the age of five he memorizes Tang poems, and at the age of nine, he is familiar with the four books and the Five Classics"., and Dave isAt the age of three, you can make a model airplane from cardboard.
Higher-than-average intelligence makes Dave prefer challenging things, and the mystery of the unknown is very appealing to Dave.
When the mysterious thing reveals its true face, it will produce psychological stimulation, and this exploration of the mystery gives Dave a strong sense of satisfaction, so he is very fond of aviation flying.
Flying in the sky greatly satisfied Dave's yearning for the mystery of the sky, so Dave followed his ideal and became a pilot, and his happiness was very simple, flying around the world in a plane, watching mountains and glaciers, lakes and oceans, and ......
If you want to ask the most mysterious and attractive place on the planet, what is **?Then one is the vast and boundless sky, and the other must be the ocean, which occupies about 71% of the earth's area.
Dave's work as a pilot has satisfied his curiosity and exploration of the sky, so diving has unexpectedly become more attractive to him than flying.
In 1999, 45-year-old Dave took his 17-year-old son to the Philippines for a vacation, and no one knew that this vacation would change his hobby for the rest of his life. During this trip to the Philippines, Dave tried diving for the first time, and this first time was like pushing the door to a new world, and his love for diving was uncontrollable.
Diving sports. Although Dave is no longer young, he has a heart that never stops exploring new things.
Diving deep into the ocean, Dave saw underwater landscapes that he had never seen before, which allowed himI was blown away, and the feeling of weightlessness underwater also made him feelStimulationDave had the passion to return to being a teenager, so he began to learn various diving techniques.
Dave'sCleverwithTalentAt this moment, it is evident that the various skills of diving are at the fingertips of Dave, even at his relatively old ageBut he is not inferior to the divers who are younger than him, and even because of Dave's work experience, he seems to be more experienced than the younger divers.
Soon, Dave was not content with diving in open water, and he began to dive and explore old shipwrecks and unknown caves, which fascinated him.
Dave is learning to dive.
In 2002,Dave traveled to Komati Springs in South Africa to further learn the technique of cave diving, as the underwater route of Komati Springs is complex and reaches high depths186 meters, so it is a must-go diving mecca for all cave diving enthusiasts, and Dave learns cave diving in this kind of placeHis diving skills improved dramatically and he broke the record for diving at Komatti Springs to reach the bottom of 186 meters.
Komatti Springs underwater.
While learning to dive, Dave also met and himself"Affection".Cave diving enthusiastsDon SheillyDon's diving skills are also very superb, so the diving exercise has made the two of them form a deep friendship, and Dave and Don have become good companions in cave diving.
In 2004, Dave and Don agreed to dive to the world's third-deepest freshwater cave, Bushman Cave, and it was during this dive that Dave made ......an amazing discovery
Don SheillyLocated in the Northern Cape province of South Africa, the Bushman Underwater Cave is a large and small area that adds to the mystery of the inaccessible underwater caves.
Dave and Don made all the preparations for the cave dive, and the two of them couldn't wait to come to the rumored Bushman Cave, which was in one of the cavesThe base of a steep cliffThere was not a sound here, except for the occasional bird's cry and the wind whistling between the steep mountain walls.
There is a layer floating on the surface of the water of the Bushman CaveDark green floating algae, which adds a touch of eerie silence to the already quiet cliff bottom, and there is a saying among the older generation in China: That is, the green water will be very deep and prone to accidents.
The surface of the Bushman Caves.
The Bushman Cave also seems to confirm this statement, because it has a deep depth283 meters, Dave came this time to break his highest record and want to dive in283 metersdepth.
Completely ready, Dave put on his equipment and began to enter the water, the water drowning Dave inch by inch, and Dave fell into the darkness little by littleQuiet, lonely, dark, which is what Dave feels every time he divesFeeling of weightlessnessSlowly enveloping Dave, he struggled to keep his breath steady and swam towards the water like a fish.
The interior of the Bushman Cave is peculiar in shapeIt is like a vase with a narrow bottle mouth, with a narrow entrance above and an open space belowSuch a structure makes this underwater cave more than other underwater cavesMore depressing, and what can be seen underwaterShorter light,So once you get into the water, all you can see is where the searchlight shines in your hand.

Dave is very confident,Rich experiencewithStrong psychological qualitiesIgnoring the darkness of the abyss, he swam down to the bottom without fear, and his ears heard his own very steady breathing, and Dave soon dived to the bottom of the cave270 metersdepth.
You have to know that in the water, for every 100 meters of dive, the pressure increases by 1,000,000 Pa when Dave dives270 metersThe body was already under tremendous pressure, but that didn't stop Dave from continuing to sneak downwards just as he arrived271 meterstime, a shocking scene suddenly appeared in front of the searchlight.
Bathman Cave water conditions.
Through the dim searchlight, Dave faintly spotted a skeletal head and armsThis is the remains of a victimThe discovery that the body was buried in the mud and sand with the respirator made Dave's breath shorten, and he tried to pull the body out of the mud, but was unsuccessful.
The huge range of motion makes Dave's breathing irregular, because the cave dive uses a closed-circuit recirculating ventilator, which recycles the exhaled carbon dioxide to each other and exhales oxygen, so if you can't maintain regular breathing, it will be life-threatening.
Dave forced his mind, he knew that he couldn't transport the remains on his own, so he adjusted his breathing and began to decompress and float steadilyAfter 9 hours and 40 minutesDave finally managed to emerge from the water.
Dave told Don about his discovery at the bottom of the cave and made a bold decisionThey wanted to help recover the remains of the victims from the bottom of the cave.
Can this salvage plan, which is so difficult that it endangers one's own life, succeed?
Figure ** on the network.
After Dave dived out of the bottom of the cave, he learned that the remains at the bottom of the cave were killed here 10 years agoDern Dreel.
In 1994, Deen and his companions died in an accident while diving in the Bushman Cave, but his body was never found, and Dave found the remains at the bottom of the cave where Deen had been sleeping for 10 years.
Dave was so sympathetic to Deen's plight that he contacted Deen's family and told them what he had found at the bottom of the cave, and he swore to Dave's family"Trust me, I'll definitely bring Deen back! ”
The place where the corpses are present is underwater271 metersThe human body has to endure strong pressure here, and Dave does not know the specific situation at the bottom of the cave, not to mention that the body is buried in the mud and sand, which makes it extremely difficult to salvage.
January 2005Dave and Don are ready to come to Bushman Cave again, this time they are well prepared, and they have also gathered 7 experienced divers to complete itDaveIn271 metersThe remains are put into a bag, and then float up, float up220 metersCausesDonTake the bag and continue to float and arrive150 metersRelay change againAdditional divers.
With a well-prepared plan, Dave is determined to bring Deen's remains to the surface at the bottom of the cave this time, will the salvage be successful?
Salvage relay plan.
The day before the salvage plan was implemented, Dave said to his fellow friend Don:"If I have an accident, please don't save me. ”
As planned, Dave put on his equipment, took the bag containing the remains, and submerged into the water little by little, the light gradually disappeared overhead, and Dave's eyes were very fastPlunged into darknessHe cautiously took the searchlight and dived underwater, and the dive went very smoothlyOnly 11 minutes, and he managed to reach the bottom of the cave271 meters.
Dave searched for Deen's remains as planned, and with the memory of the last time, Dave quickly found his target, and most of Deen's body was buried in mud and sandBut when Dern pulled the body out of the mud and sand, something unexpected happened!
Dean's corpse was not fully skeletonized, the moment the corpse was pulled out, it began to flutter, the sudden situation made Dave a little nervous, he tried to put Denn's corpse in a bag, but it was unsuccessful, one, two, three, Dave's breathing began to become tight.
In this critical moment, something worse has happened! Dave's searchlight gets tangled in a guide rope in the water! This sudden situation made Dave even more nervous, and he took out the scissors he was traveling with him, trying to cut the guide rope that was wrapped around the searchlight, but there he was"I can't see my fingers".In the darkness, Dave's handsKeep groping, but alwaysDidn't cut anything.
The tremendous pressure underwater, the long stay, and the clenched and restless breathing of the water, Dave quickly lost consciousness and plunged the world into darkness......
Don found that Dave did not rise within the agreed time, which gave him a bad premonition, although he had agreed that Dave would not dive if there was an accident and that Don would start to float on his own, but the deep friendship still made Don continue to dive despite the agreement.
In the vast darkness, Don noticed a faint light under the water, but the light never changed, and when he wanted to continue diving, this light was like a candle in the windCompletely extinguished.
Figure ** on the network.
Don knew that Dave was killed, and his breathing began to become no longer smooth, at this time there was a sharp ** in Don's ear, and the hammer controller of the rebreather was damaged, in this case, in order to ensure breathing, Don had to manually inject oxygen into the rebreather, and the concentration of oxygen needed to be monitored in real time.
Don knew that he would die here if he didn't float again, he looked in the direction of the searchlight with tears in his eyes, silently said his final goodbye to Dave, he adjusted his breathing, and began to decompress and float aloneAfter 10 hours of ascent, will he be able to leave successfully?
Don floats up the simulation.
The divers who met Dave and Don above found that no one had successfully ascended to a fixed position within the agreed time, and when they looked down, it was the darkness of the black hole, and there must have been an accident underwater!
After the divers waiting on land learned the news, they began to go into the water to rescue, and then in the process of diving, they met Don, who was lonely and difficult to surface, and Tang took out his waterproof pen and wrote on the drawing board:Dave can't come back.
The people on the ground learned about the underwater situation through the drawing board, Dave had been killed, and Don's condition was not optimistic. Because he had been underwater for too long, his body could no longer withstand the tremendous pressure, so he no longer thought about itDecompression sicknessStart floating at full speed.
Decompression sickness refers to the fact that when a high-pressure situation shifts to normal air pressure, due to the rapid decompression, the dissolved gases in the blood will be released, and a large number of bubbles will form in the blood, which will cause irreversible damage to the human body.
Minutes and seconds passed, and Don reached underwater50 metersAt that time, his head had begun to faint. His strength had begun to be lost, but the strong desire to survive made Don grasp the guide rope and not lose his way in the darkness.
Nausea, vomiting, dizziness,Because of the rapid decompression, his body began to experience serious discomfort, but Tang never gave up, and living became his last belief! In the end, Don managed to reach underwater6 metersplace, by this time he was already thereExhausted, the body has beenCompletely uncontrolled,Other divers helped him at this time, and finally managed to reach the surface.
The salvage plan failed ......
The people on the ground were all silent when they knew that Dave had been killed at the bottom of the cave, and they wereHeartbreaking, and on one side againOverwhelmed, because the site where Dave and Deen were killed was 271 meters underwater, and none of the divers had the ability to recover their bodies.
Don also suffered from irreversible decompression disorder because of the rapid ascent, and the gloom was bleak, and the sadness filled everyone's hearts at once, and after discussion, everyone unanimously decided to leave Dave at the bottom of the cave, and also held a memorial service for him on the shore.
Discover Dave. It was supposed to come to an end, but it was Dave who was killed3 days later, that is12 January 2005, when people clean the guide rope underwater, underwater20 metersDave was found dead.
Dave's hands were wide open, his body and the back of his head were pressed against the rock wall, and there were some guide ropes wrapped around his body, and to his surprise, there was a bag next to Dave, and the bag contained Dern sleeping underwater10 yearsof the remains.
Dave was found on camera footage to find Dean.
Dave fulfilled his promise with the help of his own"Corpse".Succeeded in bringing Deen up, but in the boundless darkness, did he know his end? If so, what kind of courage is this?
Eventually, Dave was buried in the sea he loved, and he fulfilled his promise to return Deen to earth with his life.
Is this fate? Or is it fate?
