What did the UFO look like, shape/size in relation to
terrestrial objects/lights/colour :
Circular looking orbs seemed to be at quite a distance away so size difficult to judge.
Did the UFO do any
strange things like hover and then zoom off quickly :
There were between 40-50 of the orbs and they appeared in one part of the sky, travelled across for 20-30 seconds and dissapeared. A passenger plain must have also experienced the objects as it flew through them.
