In this video, we uncover the Everest climb, where a couple's summit dream collided with the brutal realities of the death zone. Driven by ambition, pressure, and overconfidence, the mountain tested every limit of their trust, judgment, and endurance. What followed was a single choice in the thinning air that would haunt everyone who witnessed it.
It was May 20th, 2017, and the South Pole of Mount Everest lay frozen beneath the night sky at 26,000 ft above sea level. Temperatures hovered near -15° F as steady winds swept across the exposed, windcoured saddle between Everest and Lots. The summit push into the death zone had begun under cold, dark, and heavily windcoured conditions.
Giani Mando, 29, was an ICU nurse at Seattle Children's Hospital, accustomed to long shifts in the cardiac unit where careful monitoring and precise decisions could determine a patients outcome. Roji Ang, 34, was a civil engineer from Boise who designed water treatment facilities and approached climbing with the same analytical mindset he used in his work, keeping detailed gear lists and route plans throughout the expedition. The two had met 3 years earlier during a mountaineers training course on Mount Reineer and later climbed Aken Kagwa together in 2015, gaining the high altitude experience that eventually led them to attempt Everest.
Their decision to climb the world's highest mountain developed gradually from shared goals and financial planning. The expedition cost could be covered using their combined savings if their wedding reception was postponed. Roi's engineering leave was limited to 6 weeks, while Giane arranged coverage for her ICU shifts through the end of May. The narrow schedule meant they could not wait for ideal weather or reschedule the expedition.
Outside the tent, headlamps moved slowly across darkness as other teams prepared for their summit attempts. Forecast models predicted a short high-pressure weather window of roughly 36 hours before the next western storm system arrived. South Pole temperatures were expected to remain near -15° F, dropping lower on the upper mountain, while wind speeds could reach 50 mph in gusts.
Roi's radio crackled intermittently with weather updates and team communications, but the battery indicator showed only two remaining bars. The device had been used extensively during the previous week for coordination with base camp and Sherpa guide Pembbea, who had successfully summited Everest six times. The radio served as their primary link to other expedition members on the mountain.
They emerged from their tent into air so cold it seemed to crystallize in their lungs. Roi's breathing was labored, each exhalation forming a cloud of vapor that froze instantly on his balaclava. He adjusted his oxygen mask, checking the seal around his nose and mouth. The regulator showed a flow rate of 2 L per minute, conservative for the death zone, but necessary to preserve their limited supply.
Giane moved with fluid efficiency, her movements economical and precise. She had tested higher on the altitude tolerance assessments at base camp. Her oxygen saturation remaining stable even during the acclimatization rotations to camps 2 and three. Her aerobic capacity honed through years of trail running in the Cascade Mountains served her well in the thin air above 20,000 ft.
The fixed rope stretched upward into darkness. A highway of kernel cord anchored to the mountain with ice screws and snow pickets. Other climbers were already clipped in and moving, their headlamps creating a string of lights that disappeared into the night. Roi and Giane joined the procession, their ascenders sliding along the rope with metallic clicks that echoed off the surrounding ice.
The initial pitch from camp 4 was deceptively gentle, a gradual rise across windpacked snow that allowed them to establish a rhythm. Roi's pace was deliberate. Each step calculated to minimize energy expenditure. His boots, new over boots fitted just before the expedition, had developed a small hot spot on his left heel during the climb to camp 4. The discomfort was manageable, but required attention to his foot placement.
Gian climbed behind him, monitoring his movement and breathing. She noticed that his rest stops were becoming more frequent. brief pauses where he would lean forward on his ice ax and take several deep breaths. His oxygen saturation at base camp had consistently run five to seven percentage points lower than hers. A difference their expedition doctor had noted but deemed acceptable for the climb.
As they gained elevation, the terrain steepened and the fixed ropes became more critical for safety. The route wound through a maze of seraks and creasses, following the path of least resistance toward the balcony at 27,500 ft. Wind gust buffeted them intermittently, strong enough to require a firm grip on the rope and careful foot placement on the icy surface.
They reached a narrow bottleneck where the roots squeezed between two ice formations, forming a line of climbers waiting to pass. Roji increased his oxygen flow to 2.5 L per minute to ease the growing heaviness in his chest, accepting the faster consumption rate, while Giane kept hers at 2 L per minute to conserve supply for the descent.
Ahead, they arrived at the crowded balcony cache site where expedition teams were exchanging oxygen bottles and resting under chaotic headlamp light scattered across windblown snow and gear. Roi's oxygen bottle gauge showed approximately 1/3 remaining, consistent with their planned consumption rate to this point. He located a bottle marked with their expedition's distinctive paint code, three blue stripes on an orange background, and began the process of switching regulators. The metal fittings were cold enough to stick to bare skin, requiring careful manipulation with insulated gloves.
Gian changed the batteries in her headlamp, a precautionary measure that would ensure reliable illumination for the remainder of the climb. She also checked their emergency supplies, spare gloves, hand warmers, energy gels, and a basic first aid kit. Everything was accounted for and accessible.
The bottle Roji selected felt appropriately heavy in his hands, suggesting a full or nearly full supply of oxygen. He connected his regulator and tested the flow, feeling the familiar rush of supplemental gas through his mask. The relief was immediate. His breathing became less labored, and his vision seemed to sharpen in the thin air.
Above the balcony, the route became more technical and exposed with fixed ropes crossing steep snow slopes and rocky outcrops that required careful footing and balance. Wind strengthened with elevation, making communication difficult. So Roji and Giane relied on hand signals and rope tugs to coordinate movement. Progress slowed on narrow ledge sections as climbers waited their turn to pass while the cold deepened through their insulation, forcing constant small movements to maintain circulation.
Roji's cough became more frequent as they climbed, a harsh sound he tried to suppress because it could signal worsening high altitude illness. And Gian continued monitoring his breathing during brief rests. At elevations above 25,000 ft, the thin air placed extreme strain on the body, requiring deliberate movement and reliance on supplemental oxygen.
Later, they reached another supply cache marked by prayer flags and scattered empty oxygen bottles, where Roji rested briefly on a snow-covered rock and cleared frost from his mask's exhalation port before continuing. Giana used the break to assess their progress and remaining supplies. They were moving slower than their optimistic timeline, but faster than their conservative estimates. Roi's oxygen consumption had increased with the higher flow rate, but they still had sufficient supply to reach the summit and return to the balcony for a bottle change. The critical factor would be maintaining their current pace without further deterioration.
In Roi's condition, the route above the cash area led through a series of steep pitches and exposed ridges. The fixed ropes were essential for safety, providing both physical support and psychological reassurance in the intimidating terrain. Other climbers moved like ghosts in the darkness, their headlamps creating brief moments of illumination before disappearing into the night. The eastern horizon began to brighten as dawn approached, though temperatures remained brutally cold.
Roi's movements became more purposeful with daylight, and his rest stops grew shorter as they continued toward the south summit, a false peak marking the final technical section before the true summit. The route followed fixed ropes across steep snow and rocky terrain, where navigation without support would be dangerous, while stronger winds made progress increasingly difficult.
Near the base of the final pitch, climbers encountered a slowmoving bottleneck on technical ground, forcing frequent pauses as Roji managed his breathing and adjusted his equipment despite clear signs of physical deterioration. His glove liners had become damp with perspiration and condensation, reducing their insulating properties and increasing the risk of frostbite. He flexed his fingers frequently, trying to maintain circulation and dexterity. The simple act of operating his ascender on the fixed rope required conscious effort and careful coordination.
Gian noticed that Roie's movements were becoming less coordinated, his foot placement less precise. He would occasionally stumble on uneven terrain, catching himself with his ice ax or the fixed rope. These were subtle signs of altitude related impairment, the kind of deterioration that could progress rapidly in the death zone.
They reached the south summit at 28,500 ft where expansive views stretched across surrounding peaks. Though the moment carried little celebration because the knife edge ridge to the true summit still lay ahead. Multiple expedition teams were waiting to traverse the final ridge creating a long slow queue on technical terrain.
Roji sat on a snow-covered rock, breathing heavily, even with supplemental oxygen. While Pembbea checked his oxygen gauge, and found the supply appearing lower than expected, for their planned timeline, the possibility remained that the bottle was not fully filled, the gauge was inaccurate, or moisture contamination affected flow. Jan's oxygen consumption remained stable, allowing her to continue. But Roji faced a riskier situation as the true summit stood less than 500 vertical feet above them. With their turnaround deadline approaching later in the day, they had to choose between pushing upward with limited reserves or beginning descent preparations if bottlenecks persisted.
Roji struggled to his feet, swaying slightly as he adjusted his pack and checked his equipment. His mask had accumulated a significant amount of frost around the exhalation port, requiring careful clearing to maintain proper air flow. The simple task seemed to exhaust him, and he sat back down heavily.
Pembbea assessed the situation with the experienced eye of someone who had guided dozens of climbers through similar crises. He checked Roi's harness and safety systems, ensuring everything was properly secured. The decision to continue or retreat would ultimately rest with Roji and Giane, but Pemba's recommendation would carry significant weight.
The wind picked up as they deliberated, gusting to perhaps 40 mph and creating a wind chill that penetrated even their expedition grade insulation. Other climbers in the queue were making similar calculations, weighing the risks of continuing against the disappointment of turning back so close to their goal. Roie made the decision to continue. His oxygen supply was lower than planned, but he believed it was sufficient to reach the summit and return to the balcony where they had cashed additional bottles. The risk was manageable, he reasoned, and the opportunity might not come again.
They joined the queue for the final ridge, clipping into the fixed ropes that led across the knife edge terrain toward the summit. The exposure was extreme. Thousands of feet of empty air on both sides of the narrow ridge. Each step required complete focus and precise foot placement on the windpacked snow. The line moved slowly with frequent stops as climbers navigated the technical sections. During the weights, the cold became penetrating, seeping through their insulation and requiring constant movement to maintain circulation.
Roi's cough became more frequent and productive, a harsh sound that carried clearly in the thin air. At 10:30 a.m., they reached the Hillary Step, a near vertical rock face that represented the final technical obstacle before the summit. The fixed ropes led directly up the cliff, requiring climbers to use both hands and feet to ascend the challenging terrain. A significant bottleneck had formed as each person carefully worked through the moves.
Roi's coordination was clearly deteriorating by this point. His movements were less fluid, his balance less certain. He would pause frequently to catch his breath, leaning heavily on his ice axe or the fixed rope. The simple act of clipping and unclipping his ascender required conscious effort and careful attention. Gian climbed directly behind him, ready to provide assistance if needed. She could see the signs of altitude related impairment becoming more pronounced, the slight tremor in his hands, the way he would occasionally lose his balance on level terrain, the increasing frequency of his rest stops.
They finally cleared the Hillary step and began the final approach to the summit. The terrain was less technical, but still required careful attention to route finding and safety. The summit pyramid rose ahead of them. A windscoured dome of snow and ice that represented the highest point on Earth. Roji's pace had slowed significantly by this point. Each step seemed to require enormous effort, and his rest stops were becoming longer and more frequent. His oxygen gauge showed critically low levels, but the summit was now within reach. Perhaps 30 minutes of climbing time under normal conditions.
They reached the summit of Mount Everest, a small and crowded platform marked by prayer flags and remnants left by previous expeditions. The view was striking, but felt subdued after the intense physical and mental effort required to arrive there. Roji sat heavily in the snow, breathing with difficulty even while using supplemental oxygen, and Gian grew concerned about his ability to descend safely. They took the required summit photographs, but the moment carried little celebration because the descent would be the most dangerous part of the climb.
They soon began moving downward along the knife edge ridge where Roi's condition continued to worsen with increasing imbalance, slower movements, and declining coordination on the technical terrain. At the Hillary step, the descent proved even more challenging than the ascent. The exposure was intimidating, and the need to face outward while repelling required precise technique and steady nerves. Roji struggled with the rope work, his movement slow and deliberate as he fought against the effects of altitude and exhaustion. The cue for the descent was as congested as it had been for the ascent with climbers moving slowly through the technical sections. During the weights, Roji would sit heavily in the snow, his head hanging forward as he struggled to catch his breath. His oxygen supply was now critically low with perhaps 30 minutes of flow remaining at his current consumption rate.
They reached the south summit and began the traverse toward the main descent route. Moving along a narrow exposed ridge with steep drops on both sides. While the fixed ropes provided some security, the terrain demanded constant focus and precise foot placement. Roi's foot caught on a wind sculpted patch of hard snow, causing him to stumble forward before catching himself with his ice ax, a clear sign that his coordination and balance were deteriorating. Gian moved closer in case immediate assistance was needed. The travers continued across technical ground with rocky outcrops and steep snow slopes, but Roie's pace had slowed significantly. Each step requiring great effort and longer rests.
His oxygen supply eventually ran out, and the sudden loss of supplemental gas made his breathing more labored, while his movements became slower and increasingly uncoordinated as they remained several hundred feet above the balcony cache. Pembbea assessed the situation and made a critical decision. He would descend quickly to the balcony with Giani to retrieve a fresh oxygen bottle while Roji remained clipped to the fixed rope at a secure anchor point. The plan was risky, leaving Roji alone at altitude while his condition deteriorated, but it offered the best chance of getting him the oxygen he needed to continue the descent safely.
Roji was secured to a solid anchor with multiple slings and carabiners. His position protected from the wind by a small rock outcrop. He was conscious and responsive, but clearly struggling with the effects of oxygen deprivation. His speech was slurred and his movements were slow and deliberate. Gian and Pembbea began their descent toward the balcony, moving as quickly as safety would allow on the technical terrain. The cached bottles were approximately 45 minutes away under normal conditions, but they pushed the pace despite the risks involved in rapid movement at altitude.
The balcony cash site was in chaos when they arrived. Multiple expedition teams had accessed their supplies throughout the day, and bottles were scattered across the area. Some were clearly empty, others were partially used, and a few appeared to be full. The identification markings were partially obscured by windblown snow and frost. Gian and Pembbea searched through the scattered bottles, looking for one with their expedition's distinctive paint markings. They found several candidates, but the weight test, lifting each bottle to assess its contents, revealed that some were not as full as expected. The labeling system had broken down in the chaos of Summit Day, with bottles from different teams becoming mixed together. After several minutes of searching, they located a bottle that felt appropriately heavy and bore markings that suggested it was from their cash. The regulator connection was clean and the gauge showed full pressure. It appeared to be exactly what Roji needed to continue his descent safely.
The return climbed to Roi's position took longer than expected. The technical terrain required careful movement, and both Gian and Pemba were feeling the effects of their rapid descent and reassent. The additional weight of the oxygen bottle made the climbing more challenging, but they pushed forward with growing urgency. When they reached the anchor point where Roi had been secured, he was no longer there. The slings and carabiners remained clipped to the fixed rope, but Roi was gone. Scuff marks in the snow suggested movement downslope, and a single glove lay partially buried several yards below the anchor point. The fixed rope showed fresh abrasion marks where it passed over a sharp rock edge. And the angle of the terrain suggested that Roi had somehow become unclipped from his anchor and slid down the steep face below the traverse. The distance was significant, perhaps several hundred feet of steep rocky terrain that would be impossible to survive.
Gian called out Ro's name, her voice carrying across the windcoured landscape. There was no response. Pembbea used his radio to contact other teams in the area, asking if anyone had seen Roi or could assist with a search. The responses were negative. No one had observed him moving from the anchor point. The terrain below the traverse was too steep and technical for an immediate rescue attempt. The risk of additional accidents was too high, and the approaching afternoon weather made conditions increasingly dangerous. Other climbers descending past the area reported seeing a motionless figure behind a rock formation several hundred feet below, but the location was inaccessible without specialized rescue equipment.
Search and recovery operations along the South Summit Traverse were suspended due to extreme exposure, high winds, and the high probability of secondary accidents to rescue personnel. Climbers descending past the area later confirmed the presence of a motionless figure below the traverse, but the terrain remained too steep and technical for immediate access. Expedition leaders determined that recovery efforts would have to wait for a period of stable weather and specialized high altitude support.
2 days later, when conditions improved, Sherpa workers reached the location and confirmed Roie's death. The body was carefully relocated to a more accessible slope before being transported to camp 2, where a helicopter longline operation later carried it to Cathmandeue for medical examination. Pathologists documented cerebral and pulmonary edema consistent with severe altitude illness compounded by hypothermia. External examination also noted frostbite injuries to the fingers and nose, minor abrasions along the torso consistent with a sliding descent, and pressure marks associated with climbing harness straps.
Investigation reports concluded that multiple factors may have contributed to the fatal descent failure. Testing of Roie's oxygen regulator showed internal icing that could have restricted gas flow, while the cylinder he switched to at the balcony cache was measured as underfilled despite its pressure reading. Inventory records suggested that oxygen bottles from different expedition teams became mixed during the crowded summit day, and at least one depleted cylinder may have been mistakenly returned upright to the cache before Roi selected it. Authorities later stated that recovery of the body from the steep rock face was not feasible using standard high altitude rescue methods.
Gian and Pemba descended to camp 4 later that day with other climbers carrying the unused oxygen bottle back into expedition storage. Weather conditions deteriorated as predicted the following evening, confirming the narrowness of the climbing window. Roji's death was officially recorded as resulting from high altitude illness and a fall during technical descent along the South Summit Traverse.
