At ca. 10:45pm-11pm we were somewhere close to Olomouc area on the Highway when all 4 of us saw a strange object in the sky. It was big and round, white lights and I think 1 red light in the middle, flying very close to us, evidently looking like a Ufo. All of us yelled 'an Ufo!' in the same time analyzing it for around 45seconds before it disappeared.
