Two objects seen in Berlin Germany

Seen comming out of the S.S.W. flying toward Zehlendorf.Two orangered with some blue color objects flying slow.They passed twice,through the flight path from Schonefeld Airport ,but did not blink with any lights from an aircraft.On the first pass,they just hoverd and flew very slow toward the Zehlendorfer city center.Then in a few moments they were back to the S.W.again,and flew the same pattern again, I had time to grab my feildglasses and check them out and took a few pictures with my cell phone then they vanished.
