This is an app and page that shows all non-military flights around the world. Interesting to me to see all the aircraft and where they heading to or coming from. I've always been interested in planes and think that a job with an airline traveling the world would be great (coronavirus notwithstanding) to see and experience what is out there on this thing called earth provided the $$ is enough. So my office has a window that faces one of the flight paths of the local airport. So I will occasionally look out at a contrail or incoming and go the this page, click on a plane, and see Paris to LA or London to Las Vegas. Panned around the map and saw a plane symbol I was not familiar with and turns out to be a P-51D Mustang.
