Ground Stop Watch - Live and replayable FAA ground stop flight map

Show HN: Live map of U.S. flights during tonight's FAA nationwide ground stop

Ground Stop Watch is an independent, unofficial live map that tracks U.S. commercial flights during the FAA nationwide ground stop. Built on the adsb.fi community ADS-B network and the FAA NAS Status feed, it shows airborne aircraft by altitude, airport departure backlogs, carrier-by-carrier comparisons to the previous week, and a draggable timeline for replaying any moment. It solves the problem of understanding a fast-moving aviation crisis by turning raw tracking data into clear, real-time context—no FAA affiliation required.
