clipped from: www.telegraph.co.uk Jim O'Neill was flying his Cessna plane at 15,000 feet when he suddenly lost his sight while suffering a stroke last Friday.
The 65-year-old, who had taken off from Prestwick airport and was on his way to Colchester in Essex, radioed for help and the RAF responded, sending a jet to his aid.
The military aircraft flew alongside Mr O'Neill and guided him down to land at RAF Linton-on-Ouse in north Yorkshire.
He was taken to hospital where doctors discovered that the stroke had caused blood the back of his head to put pressure on the optic nerve, blinding him.
