Wings of Yesteryear

What is an aircraft book doing at the national postal museum library? Airplanes have also carried the mail—and continue to do so. The golden age of private aircraft spanned the end of World War I to the start of World War II. During these years of temporary calm, aircraft engineers made significant technological advances, producing safer, stronger, and faster aircraft. Many of these innovations appeared in aircraft made for the private market. The book’s dust cover features an impressive example: a Waco Standard Cabin series covered cabin biplane aircraft powered by a cowled radial 165-horsepower engine.
