I saw what appeared to be a dark 4-sided object, flat in appearance, with no lights, headed northeast, on the evening of 8/20/01.

On this particular night which was extremely chilly, the stars were very bright and vivid. I was looking at the stars when suddenly I was aware that there was movement overhead.  In the brightest part of the sky, the night was 'black/blue' in color but within that blue/black there appeared to be an object which appeared as brown (and maybe a dingy purple/brown).  There were no lights on this object.  It appeared as a shadow within a shadow.  I wouldn't call it triangle-shaped.  It had even sides, which flared out, and the backend portion was much wider than the front end.  It appeared to be heading northeast.  At some point it became harder to locate and I turned around hoping to catch it again but in this direction the sky was much darker as this is an area in which there are fewer city lights.  I could see nothing.  In terms of distance (?)I have been asked submit a drawing to scale, using a full moon as a comparison.  For this written description, let's say that if a seed from a lemon could be my "moon", then my object would be twice that size.  I have thought since then that perhaps what I saw was a Stealth bomber but it seems the backend of these jets are not one single straight edge and there is a definite "nose", isn't there?  And it just seems there should have been somekind of signal (light), but then Stealth bomber "facts and data" is just not my thing.
We are not certain what the time of the event was.  We do not know what a time of "21:75" implies.  PD
