Hello there! I've decided to start a new series on useful websites that will most likely make your life easier. In each post of this series, I'll introduce you to three useful websites, so let's get started.
And if you're wondering how they got this information, it's as follows:
Flightradar24 combines data from several data sources including ADS-B, MLAT and radar data. The ADS-B, MLAT, and radar data are aggregated together with schedule and flight status data from airlines and airports to create a unique flight tracking experience on www.flightradar24.com (source)
So that concludes this post; I hope you found it useful; please let me know if you think I should continue writing posts like this, and have a wonderful day.
