We were on our way home from our work , when suddenly this bright orange ball appeared in the entfernuung of 2-3 kilometers in the sky.I said it to my colleagues , look as a UFO . All in the car saw it. All in the car saw it .We saw a light orange ball for 5 seconds , he quickly moved a few feet down and disappeared.It looked as if it would end , just as we arrived in this area , where it should be , we saw nothing . I do not know if these people , dominate the possibility of camouflage ( invisibility ) , this would at least explain why it disappeared so quickly in the sky My parents had experienced an experience . That was about 30 years ago . They had just visited my sister, who spent the time near Geneva language studies.As the evening on the highway from Geneva to Zurich home tours , appeared behind 2 brightly lit windows. They were so bright that the whole surrounding area was as bright as day . They followed them for 2-3 minutes and then disappeared suddenly .
