Aeronca L-3B 'Grasshopper'
The L-3, originally designated O-58, was the military version of the Aeronca Model 65 Defender. This high-wing, light airplane could operate from small, hastily-built flying fields. The Army ordered the first O-58s in 1941 to test the use of light aircraft for liaison and observation missions in direct support of ground forces. Between 1941 and 1943, Aeronca Aircraft Corp. of Middletown, Ohio, built more than 1,400 of these aircraft for the Army -- 875 of them were L-3Bs.

History & service
During World War II, Aeronca L-3s joined similar "Grasshoppers" in artillery fire direction, courier service, front-line liaison and pilot training. In 1942 Aeronca developed the TG-5, a training glider based on the O-58. The three-seat glider had a front fuselage replacing the engine, but retained the rear fuselage, wings and tail of the powered version. Aeronca built 250 TG-5s for the Army.
Built during WWII, the L-3B on display found its way into private hands as surplus after the war. Completely restored by its previous owner, Paul Grice of Waynesville, Ohio, the airplane was flown to the museum in 1984.

Aircraft change the battlefield
In the First World War, aircraft became valuable because they could see beyond the front line. Reconnaissance and artillery observation affected decisions on the ground. Once that information mattered, opposing forces had reason to attack the aircraft gathering it. Fighters, defensive armament, and increasingly specialized missions developed around this contest over observation and freedom of movement.
The aircraft were fragile by later standards, but their crews worked inside a rapidly expanding military system. Training, maintenance, replacement aircraft, photography, communications, and weather reporting supported each sortie. Improvements in engines and armament changed tactics, while the pressures of combat exposed weaknesses that might have taken much longer to discover in peacetime.
Personal stories should be read alongside those systems. A uniform or a named aircraft connects the war to an individual, but the individual depended on many others and operated under constraints that skill could not eliminate. Aircraft from opposing sides show how designers answered similar problems in different ways. The later military collections in Dayton and at Udvar-Hazy reveal what endured: the need to gather information, protect friendly forces, move people and supplies, and coordinate action across distance. The scale changed enormously; the relationship between an aircraft's design and the job it had to perform remained fundamental.
