The Jenny, the little plane that could.
As popular as the plane was with the Army, the Jenny came into her own after the war. The government sold hundreds of surplus JN-4s, some of them still in their shipping containers, to anyone with $300 (about $4,130 today), says Jeffery S. Underwood, a historian at the United States Air Force Museum at Wright-Patterson Air Force Base in Ohio. The plane proved especially adept at barnstorming, becoming the most popular aircraft used in that daring sport. Thousands of pilots learned to fly in a Jenny, including Amelia Earhart.
