What did the UFO look like, shape/size in relation to
terrestrial objects/lights/colour :
It was like a black bean and there was no sign of a baloon gondola or a rotating blade of a helicopter so it couldn't be a helicopter and since it was day no lights were visible and it was not really big maybe because it was too high .
Did the UFO do any
strange things like hover and then zoom off quickly :
it was in one spot and it didn't move and it suddenly vanished
