I feel this thread should be more 'tongue in cheek' than serious but what are the reported 'lights in the sky'? There must be aircraft up there of which we wot not - although I very much doubt they're crewed by little green men (unless the cockpit is too warm, the maneuvers too violent and last nights curry is making an escape bid). This report seems more lucid and believable than most: Chris Gibson, who was an engineer on a North Sea Oil rig, made one of the most credible sighting of the aircraft (Aurora) in August 1989. What makes Gibson's report particularly sound is the fact that not only was there independent witness by the name of Graeme Winton but Chris Gibson was a fully trained member of the Royal Observer Corps, aircraft recognition team, for twelve years. He was considered an expert in this field and had himself written an aircraft recognition manual for the Corps. What Chris Gibson saw that day was four aircraft flying in formation, the largest of the four was a KC-135 Stratotanker, on its left flank were two F-111's and on the right was a mysterious black triangle that despite being an expert in aircraft identification, Gibson could not identify. Gibson states that this remains the only aircraft he has never been able to identify.
