Enjoy this awesome compilation of landings at Chicago O'Hare. I intentionally left in parts after the planes passed because I wanted to get that wingtip vortex sound on film too. I don't see many planespotting channels doing that even though it's just as awesome as the planes themselves.
I've noticed that out of all the planes, the 737s, 757s, A321s, 777s, 717s, 767s, and especially the CRJs make the loudest wingtip vortex sounds while the 787s, 747s, A330s, A340s, A350s, A380s, A320s, and ERJ-175s make hardly any wingtip vortex sound. Definitely would like to know why that is.
