On 05/18/2009 I was testing my new camera on my balcony. I took about 30 pictures between 16:30pm and 16:50pm with different exposure- and aperture-values. The total view of my balcony was from about 190° south to 350° north. A little time ago I sorted my pictures and on ONE of them I found a curious object, which I am not 100 percent able to explain. Due to the short range to Frankfurt Airport I think it has to be a plane, but I cannot see any wings or a tail. Line of sight was about 190-200° south, estimated distance is about 1-2 km, height of the object about 1 km.
There were no planes, helicopters or baloons on ANY of the other pictures! I've attached 3 photos: the one I took before, one after and the actual one (100_0167.jpg) with the object in the upper left area. Please keep me informed about your findings. Thank you very much.
