A pilot who suffered a stroke at the controls of his light plane found himself totally blind at 15,000ft.
Jim O'Neill, 65, was alone in the cockpit of his four-seater Cessna and frantically radioed a mayday alert.
Air traffic controllers attempted to guide him to the nearest airfield, Full Sutton, near York.
But so complete was his loss of vision that it proved to be an impossible task. Thankfully, an RAF Tucano used for
training military pilots was already in the air and was soon alongside the stricken pilot.
