Great website to check air traffic live!
With all aircraft in Northern Europe grounded and millions of passengers stranded, it is time to visit this very interesting website, that, at the time I am writing this post, shows an unusual picture of air traffic in Europe, with the only aircraft moving along the Portugal-Spain-Italy-Turkey axis...
Besides the particularity of the situation, I like this website, nice design and very easy to use, just click on any of the small airplanes on the map and you will get all the details!
