I Saw 4 oval shaped objects in the sky to the north of my houseSept. 11 2002 between 10:00 and 11:00 Pacific time I saw, in the sky north of my bedroom window above the trees in my backyard, four objects of apparently oval shape(Although I suppose they could have merely been at an angle at which they seemed oval shaped, but I digress.)They moved in an eastern direction swirling around each other in a counter clockwise direction. They moved soundlessly as far as I could tell, passed behind a fig tree in my backyard, and I did not see them reemerge from behoind the tree. They were colored a sort of greyish color that was about the color that most clouds appear at night, but these were moving far faster and in a different manner than any cloud that I have ever seen. There were no lights that I saw just a solid looking grey color on the ovals. I have lived close to an airport almost all of my life and have a passing familiarity with what planes look and sound like at night. I can't remember seeing a plane at night that close to an airport with no obvious lights anywhere on it let alone four. They were planes taking off and coming into the airport not too long before or after my sighting.This sighting took place over the course of no more than 15 or so seconds. This may sound strange but the shapes seemed to be almost two dimensional, but that is merely a personal opinion.(And I don't mean I think they came from the 2nd demension I mean they seemed to posess no depth.)((NUFORC Note: We observe that the description provided by the witness is not inconsistent with a sighting of laser-based advertising lights. However, that is a guess. PD))
