Yep, 'tis Luxembourg. I'll give you it as there's obviously only one airfield in that country that has EasyJet service
The cooling towers on the horizon, on the other hand, are in France. Luxembourg was not only occupied by the Nazis during WWII but was actually annexed, like Austria, into the German Reich. The bit of France the cooling towers are in, is Lorraine which (I think) was also part of Germany at one time, although maybe a different time to the one in which Luxembourg was.
