globe.adsbexchange.com displays ADS-B traffic from all over the US. I was playing with it today, and added a type code filter of 'RV'. It displays all the aircraft it 'sees' with a type code that starts with RV. Pretty cool!
It’s amazing technology isn’t it? I use an app called Plane Finder and you can filter by the same. Here’s a screen grab from 15 seconds ago. Really is pretty cool!
this is cool.. I've heard that the FAA uses adsbxchange sometimes to see the effect of traffic management in real time, even though it's a volunteer site.
