This. The linked article's title is "Deliverance From 27,000 Feet". It's been posted on HN four times (see https://hn.algolia.com/?query=https:%2F%2Fwww.nytimes.com%2Finteractive%2F2017%2F12%2F18%2Fsports%2Feverest-deaths.html&sort=byPopularity&prefix&page=0&dateRange=all&type=story https://hn.algolia.com/?query=https:%2F%2Fwww.nytimes.com%2F... ), but I believe first post is https://news.ycombinator.com/item?id=15951204 https://news.ycombinator.com/item?id=15951204 Although the main theme of the article is about the recovery of a body from near the summit, it has background information on when climbs can take place, and how the route to the summit is established every year. IMO, it's a worthwhile read!
