I'm watching ADSBexchange too.

It's eerie seeing the total number of aircraft tracked decrease. I put on a filter for 1000' to 80000', to exclude aircraft on the ground, and the number was around 12K when I started watching. It's down to just over 9.4K now. Wild.

Edit: 22 minutes later and the count is down to 8.4K.

If you haven’t seen it, there’s an exhibit about 9/11 at the Smithsonian Air and Space Museum in DC that shows the airspace in the lead up to and just after the attacks. If you find the traffic changes now interesting, I think you’ll find that interesting as well. It’s possible it’s online if you do some googling

		Appreciate that reference. I'll look for it. The house where I lived on 9/11 is in the approach for a runway at a local airport. Air traffic was a fixture at that house. Somebody was landing at all hours most days. It was the strangest thing to have no traffic at all back in 2001. It's odd for the absence of a thing to be jarring but it was.

		Below 6K now and the map is looking really empty here. The medical helicopters definitely stand out more now, though. Edit: I also never noticed balloons before. N804XR is kinda interesting, for example. Oh-- there are two. N804XR and N807XR. Tethered Customs and Border Patrol aerostats. I'd never heard of these things before.
