First i wanna say , is sorry for my bad english. :)Second i wanna say, its not my first sighting.Third i wanna say is, i know , how Helicopters and Airplanes look like.I often saw Airplanes and Helicopters at night and day and identify them easily, because 2 km from here was an german air force Base.Fourth is important to know that i don t exactly the Day and Month it happened. It is now about 4 Month ago.A Balloon, Zeppelin, Whether effect, Helicopter, Airplane,or IR-controlled things or anything else is not an option for my sighting. I was standing by my brothers window and looked outside because i saw a strange bright yellow Light about 6:00 - 7:30 pm .First i clearly saw, was an solid egg-like.It was very huge, it had the Dimension of two 737 in wideness.(i fly every year in 737 so i know the exact dimensions)It was in low high , i would say about 50 - 60 meter .It had absolute no sound - no noise.It was yellow- to orange not glowing but shining surface (texture) with single patterns which where seems to be lighted in yellow/white bright Lights.Colors don t changed, direction not changed and speed not changed, no noise or sound at all.It was slowly 15-30 km /h and flew straight and get out of my vision.Complete time of sighting was about 1 minute and i had enough time to get a friend and my brother to the window, so i have two witnesses.I swear this is the truth and i would like to know the truth, what this Object was. Have two eye-witnesses.
