The eruption of a volcano in Iceland has the skies over the UK and Europe filled with ash. Like what happened on 9/11 in the USA, planes are landing everywhere and staying out of the skies. Volcanic ash eats scours jet turbines, making in flight failure almost a certainty.
There’s a cool website called flightradar24.com which is operated by a volunteer network of aviation enthusiasts with special receivers. They describe it as:
Flightradar24.com shows live airplane traffic from different parts around the world. The technique to receive flight information from airplanes is called ADS-B. That means the Flightradar24.com can only show information about airplanes equipped with ADS-B transponders. Today about 60% of the passenger airplanes and only a small amount of military and private airplanes have an ADS-B transponder. Flightradar24.com has a network of about 100 ADS-B receivers around the world that receives the information from airplanes with ADS-B and sends this information to a server, and then displays this information on a map on Flightradar24.com. Only airplanes within the coverage area of the 100 receivers are visible.
Watch as airplanes disappear from the skies over the UK and Europe. Here’s about 8AM PST. Blue X’s are receivers.
