The L-1 is a high wing observation plane used by the military during WWII. Its unique ability to fly fully controllable at 28 knots and still cruse at 105 knots made it an incredibly capable observation plane. Though over 400 were built, this is the only one known to exist today. Restoration began in 1987 and was completed in 1993. This aircraft was graciously donated to the museum by Karl S. Johnstone.
