If you stand just underneath a commercial airplane as it's coming in to land (as was the case here at dfw airport) and so long as there's not a lot of noise around you (like loud traffic, etc. ) then when the jet passes overhead, what you can't see is that at the tips of the wings are rapidly spinning vortices of air that coil off the wingtips as the plane passes through air. These long, coiling spirals of air will eventually "close" and as that happens, it creates a momentary but bizarre, surreal sound that you really need to hear for yourself in person to get the full effect. This was the best i could capture on august 15th, 2022. Enjoy!.
