Casper - Live Aircraft Tracking
Casper the live tracking website has expanded its coverage. Previously Casper only showed real-time tracking of flights on Google Maps in and out of Schiphol Airport in the Netherlands. The site now also shows flights in and out of Manchester and Dublin Airports.
It is an interesting time to check out Casper. Because of an ash cloud from a volcanic eruption in Iceland all flights in and out of the UK and several other European countries have been suspended. Casper does show a handful of planes are flying in and out of Amsterdam but the UK is one big empty airspace.
If you want to check out the empty skies over Europe then have a look at Flightradar24.com. Airspace is apparently also closed in Norway, Sweden, Finland and Denmark. However Flightradar24.com does seem to show some flights venturing into the south of Sweden and Denmark.
Radar Virtuel also provide a Google Map that shows real-time aircraft traffic coverage over Europe. The Radar Virtuel site now shows less traffic over Europe as even more countries have closed down their airspace.
