Emergency Squawk Watch Screensaver
The Emergency Squawk Watch screensaver shows aircraft currently transmitting an emergency transponder code — 7700 emergency, 7600 lost radio, 7500 interference — from the open ADS-B network. An empty board is the normal, good state. It's free, runs in your browser, and ESC exits.
