A departures board for the whole world, live. Every row is a real airliner that has just left the ground somewhere: it was between 150 and 10,000 feet, climbing at 400 feet a minute or more, and heading away from the scheduled-service airport within 45 km of it. The newest take-off is at the top, and a row stays for 45 minutes. The board checks for new departures every 30 seconds.

Time is the estimated wheels-up time in UTC, worked back from altitude and climb rate when the aircraft was first seen. The flight number comes from the radio callsign, using the airline's code where the airline is known. Remarks show the aircraft's latest reported altitude. Point at a row or use the arrow keys to read its record.

The data comes from volunteers' ADS-B receivers, so busy, well-covered regions (North America, Europe, East Asia, Australia) fill the board, and places with few receivers barely appear. Only 24 common airliner types are polled, each about every four minutes, so short regional hops and some climbs are missed. The nearest airport can be wrong where airports sit close together. Destinations aren't broadcast, so the board shows where each flight left from.
