Noseless sauser, lucky witness.

It was a long time ago in Russia. I was about 6 (i am now 17). But by looking at my age don't turn away, i remember it quite clearly. Mum and i lived in a 10 storey flat and we were on the 8th floor. One night we went to our friends party in the same building and later came back with my friends for a sleep over. We were lying down in the loundge room and i was on the floor facing the window. We talked for a quite a bit that night and i didn't take notice of the time but the sun was gone and the sky turned dark blue. In the background i saw only the horison of the city and the dark blue skyes. About a minute or two after we all went quite but i kept looking at the window. Then i saw a large black object fly past our window and i said "guys, look!". I wasn't dreaming that's for sure. Every body hopped out of their beds like an alarm had just went off. Sure enough they've seen it but i layed there on the floor asking them what it was but they told me not to worry, yet they were talking about it the next day. I believe that by the time they got up and ran to see it, the object would have took off.
Becasue it was getting darker i only saw the outline of the object so i couldn't have been able to determine the shape of the object from top but by what it looked like from the side and comparing it to all the other ufo's i would have to say that it was a sauser.
The object was made up of the main body which was oval but had sharper ends (more like two dinner plates joined together) and a semi sphere on top (may have been the cocpit). The diameter of the sauser was around 4-6 metres and in height about 2-3 metres. At the base of the semi shpere (cocpit) were different flashing coloured lights, spaced out about 40-60cm from each other. The sauser was traveling at about our window level as if it was scanning our floor level. It's speed would have been approximately 10-15km/h. There was no noise at all even though the windows were open, so if it wasn't for me we would have missed it completely.
I strongly believe in the ufo after that particualr encounter but i don't think i'd like to get any closer unless they start communicating.
Date of incident is approximate.  PD
