A Cumbrian entrepreneur who was killed in his helicopter last year was 'not qualified to fly at night', a report has found.

Mark Weir, 45, from Cockermouth, died on 8 March 2011 after his helicopter crashed shortly after taking off from the Honister Slate Mine that he owned in the Lake District.

A report by the Air Accident Investigations Branch has found that Mr Weir did not hold a night-flying qualification and had taken off in 'challenging circumstances' with reduced visibility and low cloud.

The report said:

Mr Weir flew regularly between his home and the mine, which attracted 60,000 visitors a year.

The report also said there was no evidence of mechanical failure and that it was "not possible to determine the mechanism by which control was lost or disorientation occurred".
