Black triangular-shaped UFO over Kühren, Germany

One night in October 2014, a person living in Germany has spotted a black triangular-shaped UFO over Kühren, a city located in the state of Schleswig-Holstein, in the north. This object emitted three white lights at its ends and a little red at it middle. It moved very fastly and soundlessly.

Witness report:

I was at my Friends birthday party in a little village that hasn't so many street lights it was already very dark. We went outside and played hide and seek. Me and 2 other friends were hiding in a very dark place between 2 trashcans. I looked into the sky and at the stars, then there were 3 big lights in a triangle shape and a little red light in the middle. It was moving very fast and the lights were'nt flashing like airplane lights are, they were just shining continuous. It made no sounds although it was very big and near to me. It was flying in a straight line and dissapeared behind some houses after a couple seconds. When I first saw it I thought it was an airplane but like I've said the lights were'nt flashing and also there was'nt a airport anywhere near by so why should a plane this size fly so close to the ground and make no sounds. When I saw the object I felt really weird and couldn't really talk but after it was gone I asked my two friends if they've seen it too, they had but they thought it was just an airplane and they said I am mad for thinking it was an UFO. Also they did'nt really listened when I tried to explain why I thought it ws an UFO. I am still really confused what this was.
