What did the UFO look like, shape/size in relation to
terrestrial objects/lights/colour :
They were orange lights, the colour and brightness of street lights, but the shape was triangular. There were approximately 20 - 30 of them and they did not appear to be moving, or if they were, it was very slowly. They looked to be about the height of low flying aeroplanes or helicopters - maybe 8,000 feet?
Did the UFO do any
strange things like hover and then zoom off quickly :
They didn't move and I watched them as we went underneath them and then watched them in the rear view windscreen until I couldn't see them any more.
