A space shuttle like craft

I lived on a dead end street and at the end of the street is a white waist high fence, and on the other side is a man mad drop of made of concrete and flowers, and at the bottom is a street. On my street are apartments on both sides kinda like an ally. The street is about 30 to 50 feet wide, and the apartments are two story. ok, now what happen was i walked out of my house down the stairs and onto the street. I then made a right turn and began to walk to my friends house, the next apartment over up stairs - same building,and as I began to turn right and walk up his stairs something caught my eye to the right of me. I stopped to look at it, and it looked like a space shuttle maybe around 100 to 200 hundred feet... maybe up in the sky right smack dab in between the apartments. It wasn't making any sound, it was moving towards me at about maybe 5 mph and had a grey glow, but not light, just bright grey color, and not from the street lights... my street doesn't have any, just building lights. I think i must have walked under it as i walked out of my house and onto the street, it was very close!!! I then ran up my friends stairs and pounded on his door, it took him what felt like forever to answer, but when he did i got him and his brother to come outside to look... but it was gone. All we could see was blinking lights off in the distance from plains like you do any other night. I don't know what i saw, I really wish I knew. I live next to a military base, so maybe they have something to do with it... I don't know. It sounds funny... a space shuttle looking craft, but thats what I saw.
Witness indicates that the date of the sighting is approximate.  PD
