February 20, 2018, we (2 persons) were driving on the highway a1 in the direction of zürich. before we reached the town önsingen, we saw a grey small spot high in the sky, on the right sight of the highway a1, under the clouds. the object was "glued" in the sky. it didn't move at all. we took the next exit at önsingen and parked the car to observe the object for another 15 minutes. it didn't move. the other person could recognize two oval objects, one on top of the other. the object on top was bigger. there was no connection visible between them. after 15 minutes, we had to leave. the object didn't move during the whole 30 minutes of the observation. i tried to take some pictures and video recordings with an iphone. it wasn't neither an airplane, nor a balloon nor a drone. after several hours we drove the same way back. it was still daytime, but the clouds were heavier. we took the same exit at önsingen. the object was gone or invisible in the clouds. we drove "under" the presumed location for another hour, but didn't see any sign of it. at home i saw that, on the video recording, the object was visible as a really tiny grey dot in the cloudy sky. the shape was not recognizable. the person who accompagnied me, draw a sketch of the two oval shaped objects he saw.
