Stinson L-1 Vigilant

The Stinson L-1 liaison aircraft (originally designated O-49) was the military version of the civilian Stinson Model 74. It marked the transition between heavier and larger observation aircraft used by the U.S. Army Air Corps in the 1930s and the lighter liaison “grasshopper" type aircraft represented by the L-series during World War II.

Between 1939 and 1941, the Army Air Corps ordered 142 L-1s and 182 L-1As with a 13-inch longer fuselage. Equipped with full-span automatic slats on the leading edge of the wings and pilot-operated slotted flaps on the trailing edge, Vigilants were well suited for operations from short fields.

The versitile Vigilant was used for a variety of missions both in the United States and overseas during WWII, including towing training gliders, artillery spotting, liaison duty, emergency rescue, transporting supplies, special espionage missions behind Japanese lines and even for dropping light bombs. Some Vigilants were converted as ambulance aircraft, and were sometimes fitted with skis or with floats for water take-offs and landings.
