I was sitting inside my apartment with balcony open and i saw a white light passing by at a great altitude from east to west. I saw 3 planes passing by along the same rute 20 min before this but i could se the lights on them. And i know that they have them on if they are below 10 000 feet so this might have been a plane at a high altitude reflecting the sunlight. The problem is that i don't have a compass so i cant take out the direction. But the light was in a position that it could have reflected on a plane. Hard to tell. But to me it looked like a white light, cigarshaped moving fast over the sky. i Wonder if this was a plane.
