Aircraft designers have studied the flight of birds only superficially. But with slide rule and logarithm they have come close, independently, to the mechanisms that keep the bird on the wing. The masters of machines that can outfly any bird for speed or distance must admit that a bird is, in a structural sense, a small and amazingly efficient living airplane. John H. Storer explains all this in a new book, The Flight of Birds (Cranbrook Institute of Science; $2.50).
