How Flightradar24 Tracks Every Plane in the Sky

Flightradar24 has evolved from a simple Swedish curiosity into an essential global infrastructure for both aviation professionals and the general public.

Founded by Mikael Robertsson and Olov Lindberg as a side project for their travel site, the platform now utilizes a massive network of 58,000 ground-based ADS-B receivers supplemented by 66 satellites to provide a real-time picture of global air traffic.

Its significance peaks during geopolitical crises, such as the February 2026 conflict between the U.S., Israel, and Iran, where daily traffic quadrupled to 20 million visits as users tracked massive rerouting through narrow corridors in Turkey and Azerbaijan.Beyond mere tracking, the tool has provided critical data for understanding aviation tragedies like MH370 and the Germanwings crash, proving that real-time situational awareness is now a vital commodity for a connected world.
