Question: What do The Man Who Skied Down Everest and Innocence have in common?
Context: Hong, Sung Taek (Hangul: 홍성택 ; Hanja: 洪成澤 ; born 13 March 1966) is a mountaineer, adventurer, explorer and author from South Korea.  He is currently a National Geographic Explorers supported by a National Geographic explorers program and a principal of KSAF Mountaineers Academy.  He is renowned for reaching all the Three Poles and crossing the Bering Strait and Greenland for the first time.  He summited Everest in 1995, skied to the South Pole in 1994 and walked to the North Pole in 2005.  He also crossed Bering Strait by foot in 2012 (official) and crossed Greenland by dog sledding in 2011.  He was thus the first in the world to reach all the five poles (Everest, North and South Poles, Bering Straits, Greenland). Willie Benegas or Guillermo Benegas is an Argentine / US mountain climber.  He has been climbing for over 25 years and has climbed Mount Everest and Anacongua many times and also climbed many volcanos in Guatemala.  He is from Argentina (Puerto Pirámides, Chubut State) but now lives in the United States State of Utah.  In 2005, while working as a Mountain Madness guide, he was noted as being well liked and respected at EBC, and being quick to help others.  He and his brother won an award in 2003 for pioneering "The Crystal Snake" route on Nuptse.  He has also climbed himalayan mountains Manaslu, Cho Oyu and Makalu.  In an interview with one Everest climber, he recounted how Benegas went into the "dead bodies tent" to save the life a man others had given up on.  That is to say they expected him to die due to various injuries and had fluid coming out of his mouth; however, Willie managed to make an airway and rallied a group of Sherpa's to carry him down.  Within the hour they had gotten him down and helicopter evacuated out the next day.  (This was during the 2015 Mount Everest avalanches and earthquake) Hannah McKeand is an English polar explorer.  In 2006 she set the record for the fastest journey (man or woman) to the South Pole a 600 nmi journey she completed solo and in just 39 days, 9 hours and 33 minutes.  The record was broken in 2008 by Todd Carmichael of Spokane, Washington, United States.  She has also skied to the South Pole more times than anyone in history.  In March 2008 she attempted to reach the North Pole alone and unsupported but had to abandon the trip after falling through the ice and badly damaging her shoulder and back.  McKeand is a public speaker and polar consultant. Everest Base Camp is either of two base camps on opposite sides of Mount Everest (It could also be any Everest base camp on given route, but this is less common since the two main routes became standardized).  South Base Camp is in Nepal at an altitude of 5364 m ( ), and North Base Camp is in Tibet at 5150 m ( ).  These camps are rudimentary campsites on Mount Everest that are used by mountain climbers during their ascent and descent.  South Base Camp is used when climbing via the southeast ridge, while North Base Camp is used when climbing via the northeast ridge. The Man Who Skied Down Everest is a documentary about Yuichiro Miura, a Japanese alpinist who skied down Mt. Everest in 1970.  The film was produced by Canadian film maker Budge Crawley.  Miura skied 6,600 feet (2000 m) in 2 minutes and 20 seconds and fell 1320 feet down the steep Lhotse face from the Yellow Band just below the South Col.  He used a large parachute to slow his descent.  He came to a full stop just 250 ft. from the edge of a bergschrund, a large, deep crevasse where the ice shears away from the stagnant ice on the rock face and begins to move downwards as a glacier. Albeit arbitrary, the mountaineering community groups Earth's 14 mountains with summits exceeding 8000 m , referred to as eight-thousanders, as a special category of peaks defining the "top of the world."  Only an elite group of mountaineers can claim to have summited all 14 peaks and many have perished trying.  (See eight-thousanders for current list.)  Particularly since 1978 when Italian expeditionist Reinhold Messner became the first to have climbed all 14 8000m peaks, summiting the eight-thousanders has become the ultimate goal for many high altitude mountaineers.  Similarly, the ski-mountaineering community has set its sights on skiing from the summits of the "eight-thousanders."  In a 2007 interview for the film "Skiing Everest", the Tyrolean mountaineer and skier, Hans Kammerlander articulated the challenge for the ski-mountaineering community: "Almost all peaks have been reached, almost all walls have been climbed.  But seldom have the walls been skied down... It would be a lovely project if I could see someone who could ski all 8,000m peaks." Rob DesLauriers (born January 25, 1965 in Vermont) is an American businessman and property developer who was one of the originators of extreme skiing.  He has skied from the summit of Mt. Everest and developed two luxury condominium hotels at the base of Jackson Hole Mountain Resort. João José Silva Abranches Garcia, (born June 11, 1967, in Lisbon, Portugal) is a leading mountaineer in Portugal.  His main professional activities are as organizer and guide in mountaineering expeditions.  On May 18, 1999, he became the first Portuguese man to reach the summit of Mount Everest, without the use of supplementary oxygen.  Three years later, in 2002, he published a book, "A mais alta solidão" "(The highest loneliness)", in which he describes his experiences in mountain climbing, namely his 1999 expedition to Everest, where he endured bitter adversities.  Nevertheless, João Garcia continued to climb and on the 17th April 2010, he summited Annapurna without the aid of supplemental oxygen, becoming the 10th man of all time to climb all 14 eight-thousanders without bottled oxygen or Sherpas. Innocence (Thai: เด็กโต๋ , or "Dek To"), is a 2005 Thai independent documentary film directed by Areeya Chumsai and Nisa Kongsri about a boarding school for hill tribe children in Chiang Mai Province, Thailand. Alison Levine (born April 5, 1966) is an American mountain climber, sportswoman, explorer and leadership consultant.  She is the author of "On the Edge" and the executive producer of a documentary, "The Glass Ceiling".  She has ascended the highest peaks on every continent and also skied to both the North and South Poles.  In 2010, she completed the Adventure Grand Slam by reaching the summit of Mt. Everest.  She serves as an adjunct instructor at the U.S. Military Academy.
