Show the last 56 days · A flight is a run of positions with no gap longer than twenty minutes; an airport is named when the aircraft was low and within five miles of it at that end.

Positions from the adsb.lol community network (open data). A distance is the sum of the straight lines between the positions heard, so it is a little short of the true track. Positions are kept in full for 7 days and at one point every five minutes after that, for 180 days. Map: OpenFreeMap, OpenMapTiles, OpenStreetMap contributors. For understanding where an aircraft went, not for flying.
