La catastrophe de l'Everest de 1996 a été l'une des tragédies les plus meurtrières de l'histoire de l'alpinisme. 🏔️❄️ Une tempête de neige soudaine a piégé des alpinistes près du sommet, les laissant bloqués dans des températures glaciales avec peu d'oxygène. Les chefs d'expédition, dont le célèbre Rob Hall et Scott Fischer, ont lutté pour sauver leurs équipes, mais malheureusement, ils ne sont pas revenus. Certains alpinistes ont été miraculeusement secourus, tandis que d'autres ont été laissés derrière dans la tempête brutale. La catastrophe a soulevé des questions sérieuses sur les dangers de l'alpinisme commercial sur l'Everest. Encore aujourd'hui, l'histoire sert de rappel glaçant que la nature a toujours le dernier mot. 🏔️ Animation créée par Sympa.

FunTranscript
00:00The winds were roaring, the snow was swirling everywhere, and the visibility was reduced to nothing.
00:0617 climbers trapped at the top of Everest were cruelly lacking oxygen.
00:11Did they have the slightest chance of getting out?
00:13And why was this day going to mark history under the name of the Everest disaster of 1996?
00:19At the end of March of that year, an expedition of 18 people led by Rob Hall gathered in Kathmandu, Nepal.
00:27The next day, they embarked on a 9-day ascent through the Himalayan trails.
00:33On April 9, they finally reached the base camp, the starting point of the ascent of Mount Everest.
00:39The progression had been difficult, and several members of the team suffered altitude sickness.
00:44During this time, another climber, Scott Fisher, led a team of 19 people to the base camp.
00:52Upon arrival, the two groups undertook adaptation exercises to learn to breathe in an air impoverished with oxygen.
00:58In Rob's team, a climber was victim of frostbite to the toes, and his frozen throat practically prevented him from speaking.
01:06In Scott's team, a man struggled to breathe from the base camp and had to resort to bottled oxygen.
01:12One of Scott's Sherpas had another serious incident.
01:16These bearers and guides, essential to the Himalayan expeditions,
01:20are able to carry loads that can exceed twice their own weight on steep and icy reliefs.
01:26An adult in good physical condition can easily carry a backpack loaded with a quarter of his weight.
01:32In addition, Sherpas seem to have superhuman strength.
01:36They also have a remarkable ability to adapt to extreme conditions of high altitude,
01:41where pressure and oxygen retention are considerably reduced.
01:45According to scientists, this would be explained by a lower oxygen concentration in their blood,
01:50which favors muscle irrigation.
01:52It is also likely that this resistance is part of their genes.
01:56Either way, one of Scott's Sherpas suffered from a serious malaise,
02:00unable to breathe normally in this rarefied air.
02:03He had to be evacuated to a hospital, but succumbed a few weeks later.
02:08Alas, he would not be the only victim of this tragic ascent.
02:12The teams continued their progress and left the base camp on May 6,
02:16reaching camp 2 in the same day.
02:18Three days later, they reached camp 4, the last step before the summit.
02:23The goal was to reach the Everest summit, then return to camp 4 in less than 18 hours.
02:28Extending one's stay at such an altitude, especially without additional oxygen,
02:33represented a considerable risk.
02:35Meanwhile, a climber from the Taiwanese National Expedition on its way to the summit,
02:40named Shen Yunan, left his tent without properly attaching the metal crampons to his boots.
02:46Deprived of this essential hang, he slipped and fell into a deep ice crevasse
02:51on a steep section of the mountain.
02:53Although he survived, he nevertheless chose to continue his descent the next day,
02:57a decision that was fatal to him.
02:59At this stage, the teams had entered an area where the air is so poor in oxygen
03:05that the human body struggles to survive.
03:07Some climbers encountered another expedition that was already descending the mountain.
03:11These members warned them of the danger of continuing due to unfavorable weather conditions,
03:16but none of them took this warning into account.
03:19At midnight on May 10, climbers from several groups began their ascent to the summit.
03:25Each carried two extra oxygen bottles, knowing that they would be exhausted by 5 o'clock in the afternoon.
03:31They had to climb and descend without wasting time.
03:34However, the Sherpas in charge of installing the safety ropes were delayed,
03:38forcing the climbers to wait an hour on the steep slopes.
03:42In addition, some participants, less experienced, have still slowed down the whole group.
03:48Rob Hall, the leader of the first group, had given instructions to reverse between 1 and 2 o'clock in the afternoon
03:55whether they had reached the summit or not.
03:57At around 1 p.m., the first group crossed the Everest summit.
04:01However, many climbers did not respect their time limit set at 2 p.m.
04:06Scott Fischer, on his side, authorized his team to continue their ascent well after 3 p.m.
04:12Rob Hall and Doug Hansen only reached the summit at 4 p.m.,
04:16an hour too late to hope to descend safely.
04:20The weather was already deteriorating.
04:22At 3.30 p.m., a storm broke out.
04:25And at 6 p.m., it had turned into a blizzard of rare intensity.
04:30While some climbers managed to regain their camp, at 10 p.m.,
04:34half of the group was still trapped in the storm.
04:38One of the groups was blocked at 8,230 meters above sea level, only 60 meters from camp 4.
04:44Blinded by the storm, the climbers chose to regroup and wait for it to calm down.
04:49Rob Hall and Doug Hansen, on their side, found themselves immobilized near an icy and steep section,
04:55known as Hillary Spring.
04:58Hansen collapsed, and Hall remained on his side.
05:01Hansen's body was never found.
05:03Later, the Sherpas discovered the remains of other climbers scattered at different altitudes.
05:08In total, the disaster cost the lives of 8 people and caused many injured.
05:13It was the deadliest report in 24 hours on Everest.
05:17Five years later, Everest did everything to prevent Marco Siffredi from being the first to unveil his snowboard summit.
05:23The route he had initially planned for his descent was cruelly lacking snow.
05:27The French alpinist and snowboarder therefore had to choose another.
05:31After only 201 meters of descent, a snowboard fastening strap broke due to the cold.
05:37A Sherpa helped him repair it, and he finished his descent in two hours, up to 6,400 meters of altitude.
05:43The following year, Siffredi sought to reiterate his feat on another side of Everest.
05:48Although the season had been well advanced in August, it did not stop him.
05:52He reached the summit on September 8, accompanied by three Sherpas.
05:56Exhausted and faced with a changing weather, his guides advised him not to continue, but he did not listen.
06:03The Sherpas lost sight of him several times, and, at about 1,300 meters below camp 3,
06:09they saw a distant silhouette stand up one last time before disappearing into the mountains.
06:15Neither Siffredi nor the tracks of his snowboard were ever found.
06:19However, we could still hear about him, because it sometimes takes nearly a century to find traces of a disappearance on Everest.
06:26On June 8, 1924, Andrew Sandy Irvine and George Mallory embarked on an unprecedented undertaking.
06:34Reach the summit of Everest.
06:36But something went wrong, and the two men disappeared into the icy heights.
06:40No one ever knew if they had reached the summit before disappearing.
06:44If they had reached it, they would have broken a record that was officially established only 29 years later.
06:50In 1999, mountaineers discovered Mallory's body on the mountain.
06:55However, the corpse then mysteriously disappeared.
06:58Although the exact location was known, the research carried out using drones and cameras remained vain.
07:04Everything leads to believe that he had been moved, but no one knows the reason.
07:08Then, in September 2024, a team making a documentary for National Geographic made a rare discovery.
07:15A boot protruding from the ice on a glacier well below the northern face of Everest.
07:21The leather, worn and cracked, as well as the steel nails of the sole, indicated that it belonged to a distant era.
07:28Inside, a sock was sewn with a red label, where we could read AC Irvine.
07:35Confirming that these were the remains of Sandy Irvine.
07:39A few days earlier, while descending the Rongpuk glacier, the team had discovered an old oxygen bottle dating from 1933.
07:47Although it is not directly related to Mallory and Irvine's ascent,
07:51it allowed them to study the possible trajectories of objects and bodies in case of a fall on the mountain.
07:57Irvine was carrying a small Kodak camera during his ascent,
08:01and many think that the clichés he contained could provide the answer to the biggest question.
08:06Had he reached the summit before disappearing?
08:09Irvine's family members also offered DNA samples to confirm his identity.
