> You can locate such "interesting" flights right now, using your browser. Just open up ADSB Exchange Virtual Radar [1] This is really neat. However, it's only showing 10 flights in the Southwest (USA) area. O_o How come it shows nothing in the El Paso area? I find that hard to believe (also: There are none flying in OR, ID, UT, CO or NM?)

Without the filter, it shows all aircraft broadcasting ADS-B [0]. The filter procedure I outlined restricts the aircraft shown on the map only to those that have been flagged as "interesting", usually because they're related to law enforcement, government agencies, or celebrities.

    adsbexchange.com collects data from volunteers, of which there are currently fewer than 500 around the world. One person can usually only pick up aircraft within a hundred miles or so. Many "interesting" aircraft don't broadcast their position, so you won't see them on a map unless they can be triangulated (actually multilaterated)--but that requires that multiple nearby volunteers receive their signals. That's why you don't see a lot of aircraft on the map, not a failure of realism.

      Cool, I was just wondering why no one was mentioning the pink elephant in the room. > not a failure of realism. Actually it's exactly that. What you just said proves it. In reality, there are a lot more aircraft than being shown on that map due to the low number of volunteers and stealth nature of the aircraft.
