What did the UFO look like, shape/size in relation to
terrestrial objects/lights/colour :
At first I thought it was a plane- as of the light. I watched it fly past (as I have done since I moved here- we have a good view). After watching the plane for rouughly 15 seconds i realised it wasn't moving. As I studied it for a few more seconds I realised it was in fact moving- but vertically. I thought at first it may have been a hot air balloon but common sense made me realised that no sane person would have been flying one at this time of night. The object was a perfectly cylindrical "plume" of light- yellow in colour- with a small "bulb" at the top of it. At this point I called the girlfriend over to confirm I wasn't just mental, but she saw it too. The object rose a further minute till it was at a height higher than that of which planes pass the window. My girlfriend turned away for a bried moment when the object all of a sudden "vanished." Had I not been concentrating so much on it then I would have lost it but I was fixed on it. The object had turned into a perfectly circular ball of "blackness." The onject veered slightly to the left and toward us quite quickly. All of a sudden it started to accelerate horitzontally toward us. In a period of about 20 seconds, it had passed over our heads and out of our sights. As I rushed down and out of our first story flat to inspect where it should be, it had vanished completely.
Did the UFO do any
strange things like hover and then zoom off quickly :
