The Aviator is an Avatar from the Air, and appears in “Runaway’s River”.
He can fly any aeroplane that has ever been built, and fly it superbly.
The Aviator is a big fan of the Biggles stories, written by Captain W.E. Johns. He
had read all 274 Biggles stories before he was Mark’s age. He claims that he learnt
more about flying from reading those stories than he ever did from his instructor.
