I purchased one of his books "The Wheeling Stars" some time ago and was delighted to read in the intro that he had taken up hang-gliding with a first flight from a 10,000 foot peak in the French Alps at the age of seventy-eight! Respect!!
Delighted to read "living legend" , I read his bio when he was 80.... , and although men of that caliber last long I though he was gone already.
Respect and admiration , I hope someone will throw him a proper party
