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

A live interactive map tracked U.S. commercial flight activity during an FAA nationwide ground stop, displaying real-time aircraft positions, airport departure rates compared to the previous week, and recovery metrics across major airports. The visualization pulled data from community ADS-B networks and FAA feeds to show which flights remained airborne, which departures were missed, and how quickly different airports resumed normal operations. The tool provided an independent, unofficial view of the shutdown's impact by tracking actual flight movements rather than relying solely on official announcements.
