Like in the movie, Rob Hall spoke to his wife on his radio via a satellite connection patched through by Helen Wilton from a mountainside campsite roughly 8,000 ft below him. He had spent the night of the blizzard on an outcrop that was about 400 ft below Everest's 29,029-ft summit. Alone in the brutal-cold near-oxygen-free air, Hall had come to terms with the realization that he was going to die. As in the Everest movie, the true story confirms that after naming their unborn baby "Sarah," he told his wife Jan, "I love you. Sleep well, my sweetheart. Please don't worry too much." That was the last time anyone heard from Hall. -TIME.com

Eight people died during the Mount Everest disaster that unfolded May 10-11, 1996. The fatalities included Scott Fischer, Rob Hall, Andy Harris, Doug Hansen, Yasuko Namba, Tsewang Samanla, Dorje Morup, and Tsewang Paljor. In fact-checking the Everest movie, we learned of the unidentified corpse known as Green Boots (pictured below), who is commonly believed to be Tsewang Paljor, one of the eight who perished in the Mount Everest disaster. Paljor was a constable with the Indo-Tibetan Border Police and was part of a three-man expedition attempting to become the first Indian team to reach the top of Everest from the northeastern route. He was wearing green Koflach boots on the day his team summited in 1996.

While researching the Everest true story, we learned that more than 150 bodies remain on Mount Everest today. Almost all of them are located in the Death Zone, where such harsh conditions make recovering the bodies a suicidal endeavor. A Nepalese police inspector and a Sherpa learned this lesson the hard way when they fell to their deaths while trying to recover the body of Hannelore Schmatz in 1984. Hannelore had died of exhaustion in 1979 when she was just a hundred meters from Camp IV. For years, climbers taking the southern route could see Hannelore's body sitting upright against her backpack, her eyes open and her brown hair blowing in the wind. In the late 1990s, high winter winds finally swept Hannelore's remains over the edge and down the Kangshung Face. -Macleans.ca

While some of these doomed climbers were lost forever in crevasses or were blown off the mountain into the void, many still remain, mummified and frozen in time. One such area just below the summit has come to be known as Rainbow Valley due to the number of corpses there still clad in their colorful climbing jackets. -Gizmodo.com

Yes, twice. Things first went wrong for Dallas pathologist Beck Weathers when the effects of high altitude and extended exposure to ultraviolet radiation blinded his eyes, which had recently been altered by radial keratotomy surgery (a precursor to LASIK). Instead of making the ascent to the summit, he eventually decided to descend and grew weaker in the storm. Anatoli Boukreev arrived later to help, but Weathers and female Japanese climber Yasuko Namba were unconscious and appeared to be beyond saving. They were left to die. At daybreak, Stuart Hutchison and two Sherpas arrived to reassess the status of Weathers and fellow climber Yasuko Namba. They concluded that both were near death and decided to leave them behind, believing they would not survive the descent.

"I woke up in the snow, opened my eyes, and directly in front of me was my ungloved right hand, which was clearly dead," Weathers remembers. "It looked like a marble sculpture of a hand. I hit it on the ice and realized that so much of my tissue was dead, I wasn't feeling any pain. That had the marvelous effect of focusing my attention. I had an innate awareness that if the cavalry was going to come rescue me they would already have been there. If I didn't stand up, I realized, I was going to spend eternity on that spot." Like in the movie, Weathers thought of his family for motivation.

Weathers made his way to Camp IV. When he arrived his hands were frozen solid and looked like a cadaver's (pictured below). His cheeks and nose where black and resembled solid ash. However, he was alive. Following his evacuation, his right arm was amputated halfway between the wrist and the elbow. His thumb and all four fingers on his left hand were removed, in addition to parts of both his feet. His nose was amputated and a new nose was grown on his forehead, which incorporated tissue from his ear. -TIME.com

As stated above, there is only a short two-week window each year in May when climbing conditions are at their best. In 1996, there was an unusually late and heavy snow pack, which had kept any yaks from reaching Base Camp, causing a multitude of climbers to make their ascent just after the yaks were able to get the supplies to the camp. This, coupled with the growing commercialization of Everest expeditions, resulted in some 33 climbers attempting to summit Everest on May 10, 1996, creating bottlenecks at the Hillary Step, the last hurdle before reaching the top (see footage of real climbers conquering the Hillary Step and reaching the top). These bottlenecks were worsened by the fact that the Sherpas and guides had not yet placed a fixed line, causing the climbers to have to wait for roughly an hour while the ropes were installed. This happened at both the Hillary Step and further down near the Balcony. As a result, many of the climbers did not reach the summit by the 2 pm turnaround time, the last safe time to make it back to Camp IV before nightfall. -Into Thin Air

A Sherpa from Rob Hall's team and another from Scott Fischer's team were supposed to head out early to attach ropes into the rock and ice to help the climbers quickly traverse the most difficult sections. However, Scott Fischer's Sherpa, Lopsang Jangbu, never showed up, and Rob Hall's Sherpa refused to work alone. Lopsang was busy towing journalist and socialite Sandy Pittman via short-rope. Jon Krakauer, fellow climber and author of Into Thin Air, says that it was "hugely important" to Scott Fischer that Sandy make it to the top. "You can't buy that kind of advertising," says Krakauer. -Dateline

Yes. Like in the Everest movie, the true story reveals that Peach Weathers was instrumental in organizing her husband's helicopter rescue. She enlisted the help of her friends and fellow moms, who began calling everyone they could think of. They contacted U.S. Senator Kay Bailey Hutchison from Texas and Tom Daschle, the Democratic Senate minority leader. Daschle encouraged the State Department to act, and they reached out to David Schensted at the embassy in Kathmandu. After Schensted was turned down by several pilots, a Nepalese woman he worked with recommended Lieutenant Colonel Madan Khatri Chhetri, a Nepalese Army pilot who she suspected might accept the challenge, and he did. -DMagazine.com

Yes. While in the throes of hypoxic dementia, Andy Harris got on the radio to tell Rob Hall that he was at the oxygen cache on the South Summit but all of the tanks were empty. Rob was high on the summit ridge trying to help Doug Hansen, who was in desperate need of oxygen. Andy was confused and in bad shape himself, not realizing that there were actually two full tanks at the South Summit cache. Mike Groom tried to radio Rob to correct Andy's mistake, but his radio was malfunctioning. -Into Thin Air

Yes, it is believed that Andy Harris (portrayed by Martin Henderson in the Everest movie) walked off the South Summit during the storm when he was disoriented from the effects of high-altitude cerebral edema (HACE). He apparently disappeared in the South Summit area near where his ice axe was found and where Doug Hansen disappeared as well. It is possible that Andy had decided to climb back up in an attempt to assist Rob Hall with an ailing Doug Hansen. The bodies of Andy Harris and Doug Hansen have not been found to date. -A Day to Die For

HACE occurs when the body fails to acclimatize at high altitudes, such as in Everest's Death Zone. Disorientation, nausea, lethargy and eventually coma and death can occur in climbers suffering from HACE.

Scott Fischer's personal friend and client Dale Kruse was suffering from altitude sickness and possible HACE at Camp I (19,898 ft). Fischer decided to climb down from Camp II (21,325 ft) to take Kruse back to Base Camp (17,500 ft) for treatment. Fischer made the 4,000-foot climb the next morning to rejoin his team at Camp II. He did not get adequate rest time before departing for Camp III (24,500 ft) with his team the next day. His ascent to Camp III was slow and when the more than 50 climbers left for Camp IV (25,938 ft) on the morning of May 9, Fischer was one of the last to depart.

Setting out for the summit (29,029 ft) just before midnight, Scott Fischer didn't arrive there until 3:30 pm, well past the 2 pm cutoff time to safely make it back to Camp IV before dark. He radioed Base Camp and told them he was weary and felt sick. He descended in the blizzard to just above the Balcony (27,559 ft), telling Lopsang Jangbu Sherpa to descend without him and to send Anatoli Boukreev up to help. Suffering from hypoxia (lack of oxygen) and most likely cerebral edema as well, Scott Fischer sat down in the route, never to get up again. When the storm subsided on May 11, two Sherpas arrived to help but it was too late. His breathing was shallow and he was not responding. They placed an oxygen mask over his face and left him be. He died before Anatoli Boukreev reached him. Boukreev lashed Fischer's backpack over his face and moved his friend's body off the climbing route (The Climb). It still remains on the mountain.

"I climbed for the wrong reasons," says Jon Krakauer, author of Into Thin Air. "I'd always wanted to do it as a kid. ... The excuse was, I was broke and I was a freelance journalist and I was getting paid well, but really, I would have paid money to go on that trip. I wanted to climb Everest, because it's Everest. I wasn't used to being guided. To be guided, you advocate your own decision making, your own judgement, you listen to what the captain of the ship orders you to do and you have to do it. The system doesn't work otherwise." Krakauer also says that it made him really uncomfortable that Sherpas were taking the risk for him. "Everest is a really different mountain than anything else," he adds. -HuffPostLive Jon Krakauer Interview

Yes, for the most part. Jon Krakauer, a journalist on assignment from Outside magazine, was originally slated to climb with Scott Fischer and his Mountain Madness team. However, Rob Hall agreed to reduce Outside magazine's fee to less-than-cost for Krakauer's spot on Hall's Adventure Consultants team. It wasn't a total loss for Scott Fischer, who was taking Sandy Hill Pittman, a wealthy socialite and former fashion editor who was working with NBC Interactive Media to stream a journal and daily video blog back to a website for schoolchildren in the United States (EverestNews.com).

Yes, the Everest true story reveals that mountaineers from the IMAX expedition discovered Rob Hall's body on their way to the summit on May 23, 1996, roughly 12 days after Hall's death from exposure. The IMAX team, which included Ed Viesturs and David Breashears, were filming the 1998 documentary Everest. The film had been in production at the time of the disaster, but shooting was postponed as the IMAX team followed Ed Viesturs up the mountain to help the stranded climbers, including Beck Weathers. The IMAX team also came across Scott Fischer's body.

Yes. The 1997 made-for-TV movie Into Thin Air: Death on Everest was also based on the book Into Thin Air by Jon Krakauer, a journalist/mountaineer who was caught in the middle of the 1996 Mount Everest disaster while on assignment for Outside magazine. Krakauer was part of Rob Hall's Adventure Consultants' expedition.
