Personal encounter with UFOs

This is a bit random post: the pics below were taken at 9:55 am, @ Humbolthein park, 01.08.09 (Berlin)...there were 10 of shiny objects in the sky, moving pretty fast in a tight formation to the south, silently.
the photos were taken by a friend of mine who was next to me at the time of the event. as you can see the sky is very clear... and very bright from the sun... which made it quite difficult to make a sharp shot.
the whole event lasted about 2-3 min... until they vanished.
