Otto Koppen left Ford to join the faculty of MIT, and in 1938, he decided that the time was ripe for an easy to fly airplane, so while teaching at MIT, he designed and set up a company to produce the Skyfarer, a two seat, two control monoplane. Koppen felt the Skyfarer needed no rudder, since its large twin vertical stabilizers were widely spaced on the tail out of the slipstream. In the air, the ball stayed centered at all times. In fact, the Skyfarer was so easy to fly that a complete novice was once taught the basics during only 50 minutes in the airplane. Twenty five Skyfarers were built; then World War II began, the Government requisitioned aluminum and production stopped.
