I´m living in northern Germany (Schleswig-Holstein) and since an hour a 4-holer is circling above us over and over again. The next airport is 150km away (HAM) and it´s flying on cruising altitude. Does somebody know what they do. I know that LH is testing the BBJ´s they furnish in Hamburg over the northsea but it´s kind of weird to me. Or is it just an E-3A Sentry and the NATO wants to spy on us?
