'UFO over airport causes speculations'.
Seems they still don't know what it was. The 'UFO' didn't appear on the radar screens - but was well-visible. Probably it was made of plastic? Or they test a 'radar-invisble' helicopter? No idea. But if you like unusual things to happen - come to Bremen! It's a nice city anyway. ;)
