SILENT, SUSPENDED WATER TOWER APPEARS OVER HOUSES IN SEA GATE, BROOKLYN, NEW YORK

In the early morning, as I was waiting for my sister to come out of the bathroom so that I could get ready for work, I was lying on the bed in my room (which used to be a porch)- because there were low windows, all I had to do was lift my head up to look outside.  
Directly across from my vision, in my two story house, hanging soundlessly and dead-center over the hip joint of my neighbor's roof, was a light tan, about 3 feet in height, water-tower (a round top with symmetrical legs) appearing object.  No lights, no sound, no movement.  
As I looked, I called my mother in and she also said "what the hell is that?"  I had an 8 mm Kodak Brownie movie camera that I always used and ran for it.  No film.  
My mother and I watched as this oject as it began to movie slowly, silently and perfectly straigt up about 30 fee and just hang there.  A couple of moments later, it started to move to the right about 30 feet also, stopped a few moments, and then go back to the center line over the house and down to the original position; waited only a few seconds this time and went straight up about 30 feet again and then to the left and slowly, slowly moved above all the 2 story houses on the block where it moved behind the trees and into the sunlight coming fromthe east.  
I then lost sight of it.  
I must stress that it was perfectly symmetrical and its movements were perfectly aligned with no wobbling, no lights and no sound.  It was absolutely suspended in mid-air.  At first we thought it was some kind of kite, but, boy-oh-boy, it sure wasn't.
Witness indicates that the date of the incident is approximate.  PD
