This picture is from ENGM. It’s interactive and close to infinitely zoomable in 360 degree view. It’s taken from the top of the tower during 1 hour of morning rush, showing all the aircraft that hour. One should be able to count 110 aircraft of different forms and sizes (mostly B737 though)
An example below (small cut out):
That is very cool! I would love to see a few more from different locations. Interesting to see the different positions of different aircraft at the same stages of flight. Even some of the same type you can clearly see the ones landing a bit long and the ones that are landing with 3 or more reds on the PAPIs.
