context_page_description: The Savoia-Marchetti SM.79 Sparviero was a three-engined Italian medium bomber developed and manufactured by aviation company Savoia-Marchetti. It could be the best-known Italian aeroplane of the Second World War. The SM.79 was easily recognizable due to its fuselage's distinctive dorsal "hump", and was reportedly well liked by its crews, who nicknamed it il gobbo maledetto.
  The SM.79 was originally developed in the early 1930s as a cantilever low-wing monoplane of combined wood and metal construction. It had been designed with the intention of producing a swift eight-passenger transport aircraft, capable of besting even the fastest of its contemporaries, but had quickly attracted the attention of the Italian government with its potential as an armed combat aircraft. Performing its first flight on 28 September 1934, early examples of the type established 26 separate world records between 1937 and 1939, qualifying it for some time as the fastest medium bomber in the world. As such, the SM.79 quickly came to be regarded as an item of national prestige in Fascist Italy, attracting significant government support and often being deployed as an element of state propaganda.
context_section_description: The SM.79 was a cantilever low-wing monoplane trimotor, with a retractable taildragger undercarriage. The fuselage used a welded tubular steel frame structure, which was covered with duralumin on the forward section, a mixture of duralumin and plywood across the upper fuselage surface, and fabric for all of the other exterior surfaces. The wings were of all-wood construction, with trailing edge flaps and leading edge slats (Handley Page style) to offset their relatively small size. The internal structure was made of three spruce and plywood spars, linked with plywood ribs, with a skin of plywood. The wing had a dihedral of 2° 15'. The ailerons were capable of rotating through +13/-26°, and were used together with the flaps in low-speed flight and in takeoff. The aircraft's capabilities were significantly greater than its predecessor, the SM.75, with over 1,715 kW (2,300 hp) available and a high wing loading that gave it characteristics not dissimilar to a large fighter.
  The engines fitted to the main bomber version were three 582 kW (780 hp) Alfa Romeo 126 RC.34 radials, equipped with variable-pitch, all-metal three-bladed propellers. Speeds attained were around 430 km/h (270 mph) at 4,250 m (13,940 ft), with a relatively low practical ceiling of 6,500 m (21,300 ft). Cruise speed was 373 km/h (232 mph) at 5,000 m (16,000 ft), but the best cruise speed was 259 km/h (161 mph) (60% power). The landing was characterized by a 200 km/h (120 mph) final approach with the slats extended, slowing to 145 km/h (90 mph) with extension of flaps, and finally the run over the field with only 200 m (660 ft) needed to land (2,050 rpm, 644 Hg  pressure).
  The SM.79 was typically operated by a crew of five (or a crew of six upon the bomber version). The cockpit was designed for the accommodation of two pilots seated in a side-by-side configuration. Instrumentation in the central panel included oil and fuel gauges, altimeters for low and high altitude (1,000 and 8,000 m or 3,300 and 26,200 ft), clock, airspeed and vertical speed indicator, gyroscope, compass, artificial horizon, turn and bank indicator, rev counters and throttles.
