Tinfoil Pigeons is a live aircraft radar that displays every broadcasting aircraft overhead on a retro cathode ray tube scope. Designed for aviation enthusiasts, plane spotters, and anyone curious about the flights above, it transforms raw ADS-B data from a worldwide network of volunteer receivers into an intuitive, interactive radar display. The core value lies in its simplicity: enter any postcode, town, or city anywhere in the world, or use your GPS location, to instantly see all aircraft within a configurable range. Tap any blip for its full identity—aircraft type, airline, registration, altitude, speed, heading, and when available, origin and destination. No app, no account, no charge. Just you, the sky, and the truth they paint green.
The concrete problem Tinfoil Pigeons solves is the perennial frustration of hearing a jet, looking up, and having no way to identify it. Traditional flight trackers often overwhelm with data, require app installations and account sign-ups, or lack a simple interface for quick identification. Plane spotters rely on expensive scanners or cluttered websites with advertisements. For the curious observer, the barrier to knowing what is overhead is too high. Tinfoil Pigeons removes every barrier: open the site, enter a postcode or town, and see real-time blips on a beautiful retro radar. It respects privacy by not storing location data. It works immediately without sign-ups or charges. This matters because it turns an ordinary moment of curiosity into instant, satisfying knowledge, making the sky accessible to everyone without technical expertise.
The first major feature group is location entry and scanning. Users can either type a postcode, town, or city name, or tap "Use My Location" for GPS-based positioning. The system never retains location data, ensuring complete privacy. Once a location is set, the radar sweep begins, finding every aircraft broadcasting via ADS-B within a configurable range of 10, 25, 50, or 100 nautical miles. The scope displays blips at real positions relative to the user's location, with a sweep line rotating at a chosen speed. The scanning process is both nostalgic and practical, mimicking the look of vintage radar while providing live, accurate data. Users can also set the scope to standby if they want to pause updates, freeing resources without losing the session.
The second major feature is tapping to interrogate any blip for its full file. When a user taps a blip, the scope locks a reticle on it and opens a detailed panel. This panel shows the aircraft type, operator (airline or owner), registration number, altitude, speed, heading, and distance from the user's location. If route data is available from flight schedules, origin and destination airports are also displayed. Military contacts are clearly indicated as such. The Mil Highlight toggle can de-emphasize military contacts—when set to OFF, they still appear but without highlighting, keeping the scope clean while still showing all traffic. This feature gives immediate, comprehensive identification without needing external databases or subscriptions.

Additional display customization features enhance the user experience. The All Labels toggle, when OFF, keeps the scope uncluttered—blips appear without visible labels until hovered or tapped, revealing their tag. The sweep speed can be adjusted to 4, 8, or 12 seconds per rotation, allowing users to slow down for relaxed scanning or speed up for rapid updates. Sonar Ping emits a soft audio tone whenever a new aircraft enters the scope, alerting users without requiring constant visual monitoring. The entire scope display can be popped out into a separate window, enabling multitasking or full-screen viewing. These features let each user tailor the radar to their preference, environment, and specific needs.
Tinfoil Pigeons works by aggregating data from the global network of ADS-B receivers operated by volunteer enthusiasts. Aircraft transponders broadcast position, altitude, and identity signals, which are picked up by ground stations and relayed to the service. The web interface renders this data as blips on a simulated cathode ray tube display, preserving the aesthetic of classic radar screens. The workflow follows three simple steps: Locate (via postcode or GPS), Scan (the sweep catches all broadcasting contacts within the selected range), and Tap (interrogate any blip for its full file). No backend account is needed; the experience is fully functional from the first page load. The operation is entirely legal as it uses public radio broadcasts, the same flights that plane-spotters have logged for decades.
Concrete use cases abound. A plane spotter living near an airport uses the tool daily to log rare aircraft. By setting range to 25 NM and disabling Mil Highlight, they can focus on military movements without distraction. A homeowner hearing a low-flying jet opens the site, enters their postcode, and within seconds identifies the aircraft type, airline, and planned route. An aviation journalist verifies a speculative military flight by tapping a suspicious blip and confirming its military designation. A traveler waiting at a window uses the tool to identify passing aircraft, noting the registration for later research. Each scenario ends with the user gaining accurate, detailed knowledge about the aircraft sharing their airspace, satisfying curiosity instantly.
Target users include aviation enthusiasts, plane spotters, curious homeowners, travelers, military aircraft trackers, and hobbyists interested in flight data. The platform is entirely web-based, requiring no installation—it works on any browser, desktop or mobile. The service is free and does not require an account. The technology leverages ADS-B, a public radio broadcast system, making it legal and accessible. In summary, Tinfoil Pigeons delivers a live aircraft radar that is simple, private, and visually delightful, answering the age-old question of what flies overhead with a tap and a sweep. It transforms the mystery of passing aircraft into an engaging, retro-styled interactive experience that anyone can enjoy without barriers.
Aviation enthusiasts, plane spotters with a passion for logging aircraft, curious homeowners who wonder about the planes flying overhead, travelers wanting to identify flights from their window, military aircraft trackers monitoring defense traffic, hobbyists interested in live ADS-B data without technical barriers, and any person who hears a jet and wants immediate, accurate identification without app downloads or account sign-ups.
