DornierThe "flying pencil" Like other German warplanes of the larger type, the Do 17 was developed from the early 1930s in civil as well as military forms in an effort to deceive potential enemies about the type's true role as well as to provide greater marketing out- lets. The Do 17 first flew in 1934, but its fuselage was too cramped for any real commercial potential, and subsequent development was concentrated on the bomber model.

Birth of a giant
In December 1914, at the beginning of the "Great War" also known as the First World War, the British Air Board issued a requirement for a two-engined bomber capable of striking German industrial and strategic centers from distant bases. It took Handley Page a year to conceive and produce the biggest plane ever built in Britain to that time. Before the first 0/100 flew in December 1915, 40 were ordered. The first units went into service in October 1916. By the following spring, several squadrons were involved in a campaign of night bombings against enemy depots and communications centers.

Caproni's initiative

Caproni was a far sighted aeronautical company, and realized even before Italy's entry to the First World War in 1915 that bombing could be a decisive weapon. In October 1914, therefore, it flew the Ca 30 prototype of a heavy bomber with a central nacelle ending in a 100-hp (75-kW) Gnome rotary driving a pusher propeller, and two 80-hp (60-kW) Gnomes with tractor propellers at the front of the twin booms supporting the tail unit with its triple rudders.

Bell AB.205American ancestry

Built by Agusta under license from Bell, the AB.205 is a direct counterpart of the UH-1H Iroquois (Model 205) military helicopter. This differs from the earlier Model 204 versions of the celebrated "Huey" in having a longer fuselage and larger cabin for the accommodation of a heavier payload carried with the aid of a more powerful engine. In its basic form, the AB.205 is similar to the US Army's UH-1D and UH-1H, but can be configured for specialist roles such as SAR with a door-mounted rescue hoist.

B-52 replacement

In 1969 the US Air Force issued a requirement for a strategic bomber to replace the the B-52. On December 23, 1974 the prototype of the "swing- wing" B-lA first flew, and this was also the first flight for the new General Electric F101 reheated turbofan. Three other prototypes soon joined the program, but the B-1A was cancelled in June 1977.

OH-6Light observation helicopter contest

First flown in February 1963, the Hughes Model 369 prototype won the US Army's Light Observation Helicopter contest against Bell and Hiller helicopters, and was ordered into large-scale production. The OH-6 entered service in September 1966. Production was curtailed at 1,434 units out of a planned 4,000, however, when costs rose and production rate fell.

Mi-24A powerful warplane

Since it entered service in 1974, the Mi-24 has proved itself a formidable helicopter. The type was derived from the Mi-8 with the dynamic system of the Mi-14, but is considerably more agile and has stub wings for the carriage of varied ordnance whose capabilities have been demonstrated in wars as far apart as Cambodia and Angola.
