Birds in Flight
William Plane Pycraft and Roland Green
How does a bird actually stay up? W. P. Pycraft takes the question apart feather by feather: the architecture of the wing, the physics of soaring, gliding, and flapping, the difference between a swift and a soaring hawk. Written before wind tunnels, sharp with observation. For readers who have watched a gull hang motionless and wondered how.
Every copy includes a printable PDF edition, a beautifully typeset book you can print, mark up in the margins, and keep on your shelf. Yours the moment you own it.
