at the speeds this craft moved it would take a few minutes to cross the atlantic and travel from the uk to usa

myself and my father observed a circular shaped craft approach approximately 100yards away and then come to a sudden stop.It hovered and began to make a humming noise.We were so close that our main view was of the underside.It appeared to be silver in colour and at the edge glowed a two foot wide orange light,which went around the full circumference of the craft.We approached the craft and as we got nearer it made a slight hissing noise and then accelerated away at unbelievable speed.It appeared to travel 4 or 5 miles out of sight within 2 or 3 seconds.I was 8years old at the time and still to this day recall the event clearly,as does my father.We never reported it as we feared ridicule,as was so common at the time.The weather conditions were fine and clear.The craft was definately not of this planet and there was no way it could be mistaken for any military aircraft.it was also very low about 150 feet up possibly avoiding radar detection.
Source of report indicates that the date of the incident is approximate.  PD
