This reminds me of "aircraft wake snapping" or "vortex snapping", which is a very audible sound one can sometimes clearly hear shortly after a plane passes over you if it's low enough, such as on final landing approach. I seriously thought I was imagining it the first few times I experienced it - so weird to hear sound coming from apparently empty air. edit to add an example: https://www.youtube.com/watch?v=UA-NONhZIN8 https://www.youtube.com/watch?v=UA-NONhZIN8
