"Daddy" Probyn, who must be the world's
oldest licensed pilot, steps out of his Jodel at a
special gathering in Kenya last month to
celebrate his 65 flying years. He learned to fly
in 1916, and ended his service career as Commandant
of the RAF College, Cranwell, before
moving to Kenya post-war. Today he still
regularly flies his single-seat VW-powered Jodel"
