How it works
Overhead, overhead soon, where to look
When you share your location, your browser picks the 0.25° cell you're in and sends only its centre. The server asks adsb.lol for every aircraft within 40 nautical miles (about 74 km) of that centre, which always covers at least 29 nm around you.
Each plane's position is turned into metres east and north of you on a flat local plane (Earth radius 6,378,137 m; under 0.5 % error within 75 km). If a position is a few seconds old, it's moved forward by that much.
'Overhead' means you'd look up at the plane at 45° or more. 'Overhead soon' means that, flying straight at its current speed and heading, it comes within 3 km of you in the next 5 minutes; the time is rounded to whole minutes, or 'within a minute'.
The line under the answer says which way to face (16 compass points) and how many degrees above the horizon to look when the plane is closest. From 85° up, direction stops mattering, so it just says to look straight up. If nothing is about to pass over, it points at the nearest plane now.
Altitudes are shown in feet, rounded to the hundred; speeds in mph and knots. 1 ft = 0.3048 m and 1 nautical mile = 1,852 m are exact (NIST).
For curiosity only. Public ADS-B data, not for navigation or operational use. Routes are inferred from the flight number and may be wrong.

Questions
- How do you count the planes overhead?
A plane counts as overhead when you'd look up at it at 45° or more from where you stand: higher than halfway up the sky. The angle comes from the plane's altitude and its distance from you over the ground.
- Can the origin and destination be wrong?
Yes. Routes come from public route data for the flight number (VRS standing-data), so a flight number that flies somewhere else today can be wrong. A route is shown only when the plane's position fits it (near either airport or near the line between them); otherwise it says 'Route not available'.
- Is my location stored?
No. Your location is used inside your browser only; the server receives just the centre of a 0.25° cell (roughly 22 × 28 km at mid-latitudes). Nothing coordinate-like goes into the address bar, device storage or analytics. 'Seen today' keeps only aircraft type codes and the time first seen, on this device.
- Why are some planes missing?
Aircraft without ADS-B transmitters (some military and light aircraft), places with no receiver nearby, and aircraft the data provider hides don't show. When a signal drops for a while, the plane fades and disappears.
- How often does it update?
Every 10 seconds. In between, each plane keeps moving at its current speed and heading, and eases to the new position over one second when it arrives. Updates pause while the tab is hidden.
- Where does the data come from?
Positions come from adsb.lol's open data (ODbL 1.0), collected by volunteer receivers worldwide. Routes and aircraft names come from VRS standing-data (CC0), the city list from GeoNames (CC BY 4.0), and the map from OpenStreetMap and OpenFreeMap.
