Atlantic bid fails as OAP rower saved.
Geoff Allum, 65, was suffering from hypothermia and exhaustion and had to be picked up by helicopter and flown for treatment.
He completed the voyage in 1971 with his cousin, legendary rower Don Allum. This time wanted to be the oldest to go it alone.
But he sent out an SOS on Friday after getting into trouble around 50 miles from Tenerife. He had set off from nearby island of Gran Canaria the day before.
Before leaving, Geoff, of Bexhill-on-Sea, West Sussex, said: "Health issues, age and raw fear tell me I shouldn't make this journey but I can't resist taking, what is surely, my last chance."
His cousin Don was the first person to row across the Atlantic in both directions.
