  "account": "A live map showcasing U.S. flights during tonight's FAA nationwide ground stop was recently featured on Hacker News. The map utilizes data from an adsb.fi community ADS-B network, alongside the FAA's NAS Status for airport delays. It is an independent, unofficial page that is not affiliated with the FAA, and users can identify individual aircraft by hovering or tapping on a dot.\n\nThe map provides data on flight positions, airport delays, and commercial departures, allowing users to read from the tracking information rather than official announcements. Times are displayed in Eastern time, with a focus on the 30 minutes before a selected time. The data represents a comparison between the current half-hour and the same half-hour a week earlier at the 16 largest airports.\n\nAn airport is considered back to normal operations once it has held three-quarters of its usual departures for two consecutive readings. The map also shows the estimated number of commercial departures missed since 3:30 pm ET, calculated by subtracting the count for the same hours a week earlier from this week's count.\n\nOn the right side of the map, statistics are provided showing how many flights left out of the number from a week earlier, categorized by color - red indicating almost none, amber indicating reduced, and green indicating near normal levels. Each dot on the map represents departures in the last 30 minutes, with the bar indicating the share of the same time a week earlier.\n\nIt should be noted that the feed lists only airports with specific entries; during the nationwide stop, every US airport is affected, whether listed or not. The feed is updated by hand, not live, based on news reports.",
