SIGHTING REPORT UFO sighting at Brentwood Essex

At first It looked like a ballon rising in the sky at the back of my house then it stopped and started to move over the top of my house it then looked like a cigar with what looked like a very small wing barely protruding either side from the center of the craft, they looked as they would probably stabalize the craft rather like a rocket, the coulour was a very non descript brown / fawn, it did not appear to be very high, about the normal height of a small aircraft not long aster take off, size appeared to be about 10-15 ft long and about 5-7 wide with apparently no windows.

it happened very quick, I was just walking to my back door to look out into my garden, I looked up into the sky, there was a few cloud, only a little wind and it was a lovely warm day. My I caught sight of what I thought was a ballon rising in the sky at a steady rate for about 4 seconds, it then stopped dead and hovered for about 2 seconds, it then turned and revealed its shape as cigar shape, so that tells me I was originaly looking head on at the craft as it was rising, it then moved off over my house accelerating to a speed of a small aircraft instantly, there was no sound from the craft, it was when it went over my house and I went to the bottom of my garden to keep sight that it turned slightly, revealing the short stabelizer wings

I am conviced this was not any normal aircraft or ballon.
