How many times have you looked up into the sky, spotted an aircraft and wondered: “Where does it come from? Where are they going?” Or even “How high up are they and how fast do they go?”

Well, with FlightRadar24 it’s possible. You just aim your phone at the aircraft and the app will tell you, or you can just look at the map and see all aircrafts near you. To be precise, the app keeps track of all passenger aircraft that have an ADS-B transponder. Today about 60% (about 30% in USA and about 70% in Europe) of the passenger aircraft have an ADS-B transponder…

When I show this app, in any “show-me-yours-and-I’ll-show-mine”-situation, I get one of three reactions. The first reaction is: “Wow. That is amazing. So cool.”, and I totally get this reaction. The second reaction is: “Hmm… Why would you want to know any of this?”, to which I reply: “Aren’t we always wanting to learn more about what we see, when we see it? Imagine astronomy if no one cared, for example…”. The third reaction is: “That’s dangerous. What if a terrorist used this app?“, to which I go: “Well, there’s the aircraft — it’s in plain sight with or without the app”.

Regardless, the app is there for anyone interested about what’s in the sky! Here are some of its features:

  • Aircraft moving in real-time
  • Augmented reality view – identify the planes flying overhead by simply pointing your phone’s camera to the sky
  • Easy to search for a specific flight
  • Filter by airline, altitude, speed and more
  • Push notification alerts
  • Flight trails and callsigns directly on map
  • Possibility to show different aircraft icons, for different aicraft types
The below screenshots are from when I wrote this post. I spotted an aircraft from my balcony. I aimed my phone… and found out that it was a Cathay Pacific flight from Hong Kong to London. It flew on 38,000 feet at 835 km/h. I also saw that there are hundreds of flights in a radius of just some 600 km or so.
