Saw the EY ORD-AUH flight routing south of London. That's rather a long way from a Great Circle track - wonder how much longer it's going to take them?
This flight and many other N America - Gulf nonstops frequently pass over the UK en route - dependant on the Ocean tracks/ Jetstream locations.
However, interesting transits of airspace over Central UK before the airspace closed were SAS, Finnair and Aeroflot flights from N America to their home countries. They certainly were off the beaten track
Anyway, taking my anorak off, can anyone remember volcanic ash closing UK airspace before?. I can't and I've got my bus pass, so been around for a few years.
