For Mallory and Irvine sleuths and Everest buffs alike you might have an interest in a podcast episode of mine called Commercialization of Everest, The Good, The Bad and The Ugly. I was high altitude cameraman on the 1999 Mallory and Irvine expedition that discovered George Mallory. The discovery changed the trajectory of my career as a cameraman and inspirational speaker. With two expeditions to the south side of Everest in 2014 and 2016 (summited in 2016), I returned to the north in 2019 with National Geographic. The incredible film, podcast, feature article and book will be released in 2020. Here's a link to the Baker Street with Thom Pollard podcast, which focuses on the commercialization of Everest, the discovery of George Mallory, and more, using excerpts from a panel discussion that I participated in at the Boston Museum of Science in 2017: https://www.buzzsprout.com/268133/1612240-episode-20-commercialization-of-everest-the-good-the-bad-and-the-ugly?fbclid=IwAR2p9zP94QmDL66VeWDB91rk5xikZsxirLBONa2Cy4qgv0cZ8hZNYRbAUeY PHOTO: from '99 expedition, Andy Politz descending in the alpenglow at 26,000'.
