CESSNA O-1 BIRD D

During its lifetime the L-19 proved to be one of the most enduring aircraft in modern military history.
In the Korean War, the L-19 or, as it was affectionately called, "the jeep with wings," was used for a variety of missions including artillery spotting, laying communication wire, evacuating wounded, and dropping supplies and flares. It was frequently used as an observation platform for commanders in the field.
Again, during the Vietnam War, the L-19 proved itself to be irreplaceable. In a new role, the Air Force began to employ the Bird Dog and its crew as a forward air controller (FAC) for supersonic jet fighters. Flying low and slow the L-19 pilot looked for concentrations of Viet Cong while attack aircraft circled at high altitude. After spotting the enemy, the Bird Dog would "point" the attack aircraft to the target with white-phosphorus rockets.

	During the late 1940s the U.S. Army began to look for a replacement of its Piper L-4 and Stinson L-5 observation aircraft. In August 1949, in cooperation with the U.S. Air Force, the U.S. Army issued a joint specification for an all-metal, short/unimproved field aircraft capable of performing a variety of tasks.
	Among these were observation, rescue, photo-reconnaissance, and artillery fire control. Additionally, the aircraft was to be adaptable for both ski and float operations. The initial fly-off competition date was set for March 1950.
	Cessna was interested in competing for this contract. To make the deadline, that company decided to use components from the existing production Models 170 and 195. The new aircraft was designated Model 305, and was completed within 90 days. It was then flown to Wright Field in Ohio for the competition with aircraft from Piper, Temco, and Taylorcraft. Cessna won and was issued the contract on May 29, 1950, for 418 aircraft under the designation L-19A. As specified, this aircraft had the capacity to trade wheels for skis or floats and had a MK4A bomb rack under each wing.
	A steel-spring landing gear reduced ground-loop tendencies and made unimproved field operations practicable. A slotted high-lift flap along the trailing edge of each wing increased performance during slow flight and short field landings. Tests demonstrated that the L-19A could takeoff and land over an obstacle 50 feet high in as little as 167 yards.
	On June 25, 1950, the Korean War began. Cessna was immediately pressed for increased production. Other services also became interested in this versatile aircraft. It was the first all metal, high-wing, single-engined aircraft to see service in U.S. Army aviation which eventually accepted 3,105 of them. The L-19 had dual controls for the pilot and observer. Foreign nations were also finding the L-19 to be a useful aircraft. General Mark Clark named the L-19 "Bird Dog". He chose this name as it represented one of its primary missions--hunting.

After spotting the enemy, the Bird Dog would "point" the attack aircraft to the target with white-phosphorus rockets.
	In a demonstration of remarkable durability, in February 1952, an L-19 was hit by enemy anti-aircraft fire at an altitude of 6,000 feet. Twelve feet of the right wing was shot off but the pilot and observer regained control and miraculously landed the aircraft at an Air Force base. Within three hours, a new right wing had been installed and the pilot was able to fly it out to another air base for further inspection and repair.
	In response to the Army's need for an instrument trainer, Cessna modified the L-19A and began production of the TL-19D. It boasted a constant-speed propeller, significant engine modifications, and a rear cabin with a hinged instrument panel. A total of 307 TL-19Ds were delivered. The latest version of the L-19, the L-19E, was produced in 1956. In September 1962, the L-19A was re-designated the O-1A (L-19) Powered by a 213 h.p. Continental O-470-11, six-cylinder air-cooled engine, this version had electric flaps and could carry four 2.75 smoke rockets (four additional rocket launchers were added later).

	On April 30, 1975, the fall of Saigon appeared imminent. A Vietnamese Air Force major, together with his wife and five children, boarded an O-lA on the island of Con Son (off the coast of South Vietnam) and flew to the carrier USS Midway. With his fuel tanks almost empty he made an excellent carrier landing and became the first 0-lA to land on a carrier deck.
