ENORMOUS Ring-shape UFO in Germany November 2014

Footage of a gigantic ring-shaped object floating in the skies of Germany. A very low frequency bass-sound can be heard, indicating that this space-ship may be producing sound waves. The application for this sound is unclear. We could speculate that the sound is a by-product of the emission of radio-waves. Which could be intended as an EMP. This would explain the distortion and noise in the video, as if electronic devices (camera's in particular) are attempted to be eliminated. 
The appearances of big unidentifiable objects in the atmosphere of our planet are increasing in frequency. This footage proofs that yet another ship had stationed itself, for an unclear period of time, in the european sky.
