i am a co\pilot and we were flying over turkey at flight level 370 and the captain drawed our attention for an object was flying near the plane,,, it crossed quickly from left to right and then climbed up the sky in an enormous speed. surprising enough, it was not on our radar.the object was dark metalic round and there were lights all over the round eadge of it.i do not belive in ufos but what i saw was real and for i am a pilot, i know that there's no way in hell man will design something flies like this thing did.
