Point your phone at the sky and see which aircraft are up there: callsign, type, route, altitude and distance, pinned to the plane itself.
This page is not on a secure (https) address, so your phone will block the camera and sensors. Host it on https (Netlify Drop, GitHub Pages) and open that link.
Live data: community ADS-B feeds (adsb.lol, airplanes.live, adsb.fi). Routes and aircraft details: adsbdb.com. Demo traffic is simulated around you, or around Auckland if location is off. On a laptop, drag to look around.
Tap the label of a plane you can actually see.
Stand a few metres from cars, fences and poles: metal bends the compass.
Drag to move, pinch or use the slider to zoom. Centre the plane in the brackets.
