The following exert is an eye witness statement. Please read into it what you will. This has been reported to mufon who I am sure are investigating:
Pictures taken at a construction area, work place.
at that time i did not notice anything strange. no sound, no light.
i take pictures there all the time. i just saw something strange a few month after i took them while looking back at them.
as you may see in the sequence of pictures, one taken after the other, in the second one there is something strange in the sky, gone by the third picture.
