William Sladen is not the pioneer of using ultralight aircraft to train geese
to migrate
(This Week, 19 July, p 15).
That distinction belongs to Canadian
naturalist William Lishman, whose book Father Goose was published in
1996. Indeed, it was Lishman who acted as technical adviser on the film Fly
Away Home, which was based on that book.
