I saw two dark triangles 500 meters above my head as soon as i saw them i remember that i was cursing i thought that the shitty americans were trying their vehicles ... then in a few seconds the leaders were gliding and it was impossible they were too huge and they were 6 meters thick they had to stall their engines were 3 white spherical lights but they were made of electricity and did not emit noise lasted 30 seconds and then on the back while pointing towards switzerland i noticed of the square windows 2 rows of 8 light windows normal neon house and suddenly hemisphere an electric blue flash and disappeared i was shocked in front of them there was a mountain of 3000meters and even today i do not know if they are teleported or so i only know that they were not humanly conceivable
