It began with a 47-second audio clip posted to a small aviation enthusiast subreddit titled ‘r/ATC_Moments’ — a community that, before last Tuesday, had exactly 1,200 members, all of whom owned sensible khaki shorts. By Thursday morning the post had 2.3 million upvotes and r/ATC_Moments had gained 890,000 new subscribers, the vast majority of whom cannot locate the transponder on a Cessna 172 and have no intention of learning. The clip itself features her calmly guiding a nervous student pilot through a crosswind landing, her voice so impossibly soothing and cool that aviation Twitter declared it ‘the ASMR the Wright Brothers died for.’
