Four floating lights, hovered about 500m above ground then disappeared.As it's a national holiday in Switzerland, there have been fireworks all night. However, there were three lights that did not fade away like the other fireworks. When I came back with my phone I saw another about 150 degrees SW of those three. That one seemed to be coming closer, while the other three flew away from me and then disappeared. By the time I looked back to the other one, it had gone too. My mother said they might be drones, however no one flies drones through a sky full of fireworks. It was also definitely not stunt planes or anything. Just small yellowish orbs of light; seemed to glide and hover very gracefully.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information. PD))
