What happened
West Freugh ran a bombing trials range over Luce Bay, ringed by mobile radar units manned by civilian Ministry of Supply operators. On the morning of 4 April 1957, with full cloud cover, a radar at Balscalloch near Corsewall Point locked on to a large, nearly stationary echo over the sea at around 50,000 feet. A second unit at Ardwell confirmed it at the same range and height. The target hung there for about ten minutes, then climbed steeply toward 60,000 feet and moved off north-east, gathering speed. A third radar picked it up; near Newton Stewart it made a sharp turn and headed south-east toward the Isle of Man, by now reading as four smaller echoes in line astern at about 14,000 feet. The echoes were the size of a ship's, and tracking lasted 36 minutes. When civilian operators talked, the story ran worldwide, and the station commander said he had been ordered to say nothing.
The official explanation
The Air Ministry told the press, off the record, that a meteorological balloon released from Aldergrove in Northern Ireland was a possible cause, and a minister's briefing note floated a private aircraft. Researchers David Clarke and Andy Roberts later suggested a then-secret U-2 reconnaissance flight, perhaps with escorts, could account for the high, large echoes. Radar artefacts from anomalous propagation are another standard explanation for unusual tracks of that era.
The anomalous case
The government's own analysts rejected the explanations offered in public. A surviving Deputy Directorate of Intelligence (Technical) note of 30 April 1957 recorded no known aircraft or weather balloons in the area and said balloons could not explain the sudden turn and fast movement against the prevailing wind; Clarke, Roberts and Jenny Randles quote its conclusion as five reflecting objects of unidentified type and origin. A brief prepared for the Air Minister likewise said the object could not have been a balloon because it moved against the wind. Three separate radars tracked it, it was stationary for minutes before climbing, and operators judged its echo far bigger than an aircraft's, which argues against a lone U-2. Wing Commander Whitworth told the Sunday Dispatch it was an object of some substance and quite definitely not a freak. The Air Ministry refused NICAP's request for the report.
The strongest argument that this was something genuinely unknown or classified, with each claim attributed to the person who made it.
