Flightradar24 started as a hobby project in 2006 when two Swedish aviation geeks decided to build a network of ADS-B receivers in Northern and Central Europe. In 2009 we opened up the network, and made it possible for anyone with an ADS-B receiver to upload data to the network. Many parts of the world were quickly covered, but the quest to provide global ADS-B coverage is still ongoing.
