1: I stood on my balcony to witness some of the fireworks launched taht night because it was August 1. in Switzerland which is a National Day like July 4. in the USA.2: The Object just came in view during the time i watched the fireworks go off.3: I thought it may be fireworks or an airplane (i live in the landing corridor of Zurich Airport which is approx. 50km from my location.) But i realized it traveled to fast for firework or an airplane and it did not looked like anything i have witnessed around the airport before.4: It was an orange Orb (?) looked like a bright star in the Sky. It traveled in a straight line across the sky and through some clouds. The sky was cloudy so it was easy to tell that it was at cloud altitude.5: I got the feeling that it was not fireworks or an airplane. It was to quick to grab a camera or something so i continued as nothing had happend.6: I lost sight of it because it traveled across the sky and disappeared behind another house across the street from my viewpoint.
