The Macchi M.C. 72 is an experimental floatplane designed and built by the Italian aircraft company Macchi Aeronautica . The M.C. 72 held the world speed record for all aircraft for five years. In 1933 and 1934 it set world speed records for piston engine-powered seaplanes; the latter still stands.
94-471: The Macchi M.C. 72 was one of a series of seaplanes developed by Macchi Aeronautica. In the 1920s, Macchi focused on speed and on winning the Schneider Trophy . In 1922 the company hired aircraft designer Mario Castoldi to design high-speed aircraft. In 1926 the company won the trophy with the M.39 , which attained a top speed of 396 km/h (246 mph). Further aircraft, the M.52, M.52R and
188-574: A Savoia S.51 . The 1923 trophy, contested at Cowes , went to the Americans with a sleek, liquid-cooled engined craft designed by Glenn Curtiss . It used the Curtiss D-12 engine. US Navy Lieutenant David Rittenhouse won the cup, and his teammate Rutledge Irvine was second in an identical aircraft.

The United States and Germany failed to qualify. From 1915 to 1918, competition was suspended for the duration of World War I . After the war, the competition resumed in 1919 at Bournemouth where in foggy conditions

DEC invited customers and partners to each year's event as guests, and the general public watched in increasing numbers as the series grew in size and popularity. For the pilots taking part, the event became, along with the King's Cup air race , the highlight of the UK's air racing season, and regularly attracted entrants from continental Europe. DEC continued to sponsor
470-488: A United States naval aviator in an M.5 The German aircraft manufacturing company Hansa-Brandenburg built flying boats starting with the model Hansa-Brandenburg GW in 1916, and had a degree of military success with their Hansa-Brandenburg W.12 two-seat floatplane fighter the following year, being the primary aircraft flown by Imperial Germany's maritime fighter ace, Friedrich Christiansen . The Austro-Hungarian firm Lohner-Werke began building flying boats, starting with
564-652: A Wright Model B floatplane, by Frank Coffyn in 1911. The Wright Brothers, widely celebrated for their breakthrough aircraft designs, were slower to develop a seaplane; Wilbur died in 1912, and the company was bogged down in lawsuits. However, by 1913, the Wright Brother company developed the Wright Model CH Flyer. In 1913, the Wright company also came out withe Wright Model G Aerboat, which was
658-504: A broader commercial sponsorship programme designed to increase DEC's presence in the UK market at that time. DEC sponsored this revived race series from 1984 until 1991, which also marked the diamond jubilee of the final race in the original series. DEC and Infopress turned to the expertise of the Royal Aero Club's Records, Racing & Rally Association which again administered and ran the actual races. The 1981 Solent course, itself
752-467: A close approximation of the original 1929 and 1931 Schneider Trophy courses over the Solent, was also used and adapted from year to year. This sponsorship had a profound effect on the awareness and popularity of handicapped air racing in the UK and further afield, as well as markedly increasing DEC's commercial profile in the UK. The appeal of the race, its historic connections, and the fact that prize money
846-459: A feature of both flying-boat hulls and seaplane floats. The resulting aircraft would be large enough to carry sufficient fuel to fly long distances and could berth alongside ships to take on more fuel. Porte then designed a similar hull for the larger Curtiss H-12 flying boat which, while larger and more capable than the H-4s, shared failings of a weak hull and poor water handling. The combination of

Martin flew a homemade seaplane in California , setting records for distance and time. In 1911−12, François Denhaut constructed the first seaplane with a fuselage forming a hull, using various designs to give hydrodynamic lift at take-off. Its first successful flight

Porte's first design to be implemented in Felixstowe was the Felixstowe Porte Baby , a large, three-engined biplane flying boat, powered by one central pusher and two outboard tractor Rolls-Royce Eagle engines. Porte modified an H-4 with a new hull whose improved hydrodynamic qualities made taxiing, take-off and landing much more practical and called it

#17327799407151128-658: A hulled seaplane resulted in the 1913 Model E and Model F , which he called "flying-boats". In February 1911, the United States Navy took delivery of the Curtiss Model E and soon tested landings on and take-offs from ships, using the Curtiss Model D. There were experiments by aviators to adapt the Wright Model B to a water landing. The first motion picture recorded from an airplane was from
1222-681: A member of the Royal Naval Air Service . Appointed Squadron Commander of Royal Navy Air Station Hendon , he soon convinced the Admiralty of the potential of flying boats and was put in charge of the naval air station at Felixstowe in 1915. Porte persuaded the Admiralty to commandeer (and later, purchase) the America and a sister craft from Curtiss. This was followed by an order for 12 more similar aircraft, one Model H-2 and
1316-492: A minimum of 100 hours as pilot-in-command, and a valid air racing licence. Following that event, the UK subsidiary of US computer company Digital Equipment Corporation (DEC) independently decided to sponsor a long-term revival of the Schneider Trophy, with the first race held in 1984, and races held annually, with a few omissions, since then. The idea was submitted by DEC's then UK PR consultancy Infopress as part of
1410-476: A new world speed record of 610 km/h (380 mph) and won the trophy outright with a third straight win. The following days saw the winning Supermarine S.6B further break the world speed record twice, making it the first craft to break the 400 mph barrier on 29 September at an average speed of 655.8 km/h (407.5 mph). Although the British team had secured the trophy for the UK permanently with

The Curtiss Aeroplane and Motor Company independently developed its designs into the small Model F, the larger Model K (several of which were sold to the Russian Naval Air Service), and the Model C for the U.S. Navy. Curtiss, among others, also built the Felixstowe F.5 as the Curtiss F5L , based on

In Britain, Captain Edward Wakefield and Oscar Gnosspelius began to explore the feasibility of flight from water in 1908. They decided to make use of Windermere in the Lake District , England's largest lake . The latter's first attempts to fly attracted large crowds, though
1786-447: A speed of 682 km/h (424 mph). It was piloted by Warrant Officer Francesco Agello (the last qualified test pilot). Not satisfied, development continued as the aircraft's designers thought they could surpass 700 km/h (430 mph) with the M.C. 72. This was achieved on 23 October 1934, when Agello piloted the M.C. 72 at an average speed of 709.207 km/h (440.681 mph) over three passes. This record remains (as of 2019)
1880-448: A speed of 682.36 km/h (424.00 mph). Eighteen months later in the same venue, it broke the 700 km/h barrier with an average speed of 709.202 km/h (440.678 mph). Both times the plane was piloted by Francesco Agello . This speed remains the fastest speed ever attained by a piston-engined seaplane.

1974-521: A towed kite glider on floats. The first of his unpowered flights was 150 yards (140 m). He later built a powered floatplane in partnership with Louis Blériot , but the machine was unsuccessful. Other pioneers also attempted to attach floats to aircraft in Britain, Australia, France and the United States. On 28 March 1910, Frenchman Henri Fabre flew the first successful powered seaplane,
SECTION 20
#17327799407152068-839: Is sometimes used specifically to refer to a floatplane, rather than a flying boat. The word "seaplane" is used to describe two types of air/water vehicles: the floatplane and the flying boat . The term "seaplane" is used by some to mean "floatplane". This is the standard British usage. This article treats both flying boats and floatplanes as types of seaplane, in the US fashion. An amphibious aircraft can take off and land both on conventional runways and water. A true seaplane can only take off and land on water. There are amphibious flying boats and amphibious floatplanes, as well as some hybrid designs, e.g. , floatplanes with retractable floats. Modern (2019) production seaplanes range in size from flying-boat type light-sport aircraft amphibians, such as
2162-620: The Dornier Wal in 1924. The enormous Do X was powered by 12 engines and carried 170 people. It flew across the Atlantic to the Americas in 1929, It was the largest flying boat of its time, but was severely underpowered and was limited by a very low operational ceiling. Only three were built, with a variety of engines installed, in an attempt to overcome the lack of power. Two of these were sold to Italy. The military value of flying boats
2256-485: The Felixstowe F.1 . Porte's innovation of the "Felixstowe notch" enabled the craft to overcome suction from the water more quickly and break free for flight much more easily. This made operating the craft far safer and more reliable. The "notch" breakthrough would soon after evolve into a "step", with the rear section of the lower hull sharply recessed above the forward lower hull section, and that characteristic became
2350-605: The Gnome Omega -powered hydravion , a trimaran floatplane . Fabre's first successful take off and landing by a powered seaplane inspired other aviators, and he designed floats for several other flyers. The first hydro-aeroplane competition was held in Monaco in March 1912, featuring aircraft using floats from Fabre, Curtiss, Tellier and Farman. This led to the first scheduled seaplane passenger services, at Aix-les-Bains , using
2444-621: The Grande Semaine d'Aviation de Tours , in the possession of the RAF College Cranwell , is also known as the Schneider Cup. Aircraft taking part had to be seaworthy, having to float for six hours and travel about 550 yards (503m) on water. Twice during the flight they had to land on or "come in contact" with the water (which allowed contestants to carry out a fast bouncing manoeuvre). If the pontoons took on water,

In September 1919, British company Supermarine started operating the first flying-boat service in the world, from Woolston to Le Havre in France , but it was short-lived. A Curtiss NC-4 became the first airplane to fly across the Atlantic Ocean in 1919, crossing with multiple stops via the Azores . Of the four that made

In 1931 Britain met the conditions to retain the Trophy permanently; it was held at the Science Museum in South Kensington, London. Announced in 1912 by Jacques Schneider , a French financier, balloonist and aircraft enthusiast,
2820-662: The Short S.8 Calcutta . In 1928, four Supermarine Southampton flying boats of the RAF Far East flight arrived in Melbourne , Australia . The flight was considered proof that flying boats had become a reliable means of long-distance transport. In the 1930s, flying boats made it possible to have regular air transport between the U.S. and Europe, opening up new air travel routes to South America, Africa, and Asia. Foynes , Ireland and Botwood , Newfoundland and Labrador were
2914-566: The Sopwith Aviation Company produced the "Bat Boat", an aircraft with a consuta laminated hull that could operate from land or on water, which today is called an amphibious aircraft . The "Bat Boat" completed several landings on sea and on land and was duly awarded the Mortimer Singer Prize . It was the first all-British aeroplane capable of making six return flights over five miles within five hours. In

The nose enclosed an oil tank with its outside wall exposed to the airstream. The wing was all metal, with flat tubular water radiators faired into the wings. The twin floats had three radiators on the outer surfaces, the forward radiator for water and the centre and rear radiators for oil cooling. The float struts also had water radiators and another radiator
3102-556: The fuselage in the interplane gap. Wingtip pontoons were attached directly below the lower wings near their tips. The design (later developed into the Model H ) resembled Curtiss's earlier flying boats but was built considerably larger so it could carry enough fuel to cover 1,100 mi (1,800 km). The three crew members were accommodated in a fully enclosed cabin. Trials of the America began 23 June 1914 with Porte also as Chief Test Pilot; testing soon revealed serious shortcomings in

F.2, F.3, and F.5 flying boats were extensively employed by the Royal Navy for coastal patrols and to search for German U-boats . In 1918, they were towed on lighters towards the northern German ports to extend their range; on 4 June 1918, this resulted in three F.2As engaging in a dogfight with ten German seaplanes, shooting down two confirmed and four probables at no loss.

Schneider was a hydroplane racer who came from a wealthy family; his interest in aircraft began after he met Wilbur Wright in 1908, but a boating accident in 1910 crippled him and prematurely ended his racing and flying career. Schneider served as a race referee at the Monaco Hydroplane Meet in 1912, where he noted that seaplane development

The proposed Italian entrant (the Macchi M.C.72), which had pulled out of the contest due to engine problems, later went on to set two new world speed records with the help of British fuel expert Rod Banks, who had worked on the Rolls Royce R engine of the S6B. In April 1933 it set a record over Lake Garda in northern Italy with
3572-678: The Americans won again, with US pilot Jimmy Doolittle winning in a Curtiss R3C ahead of the British Gloster III and the Italian Macchi M.33 . R. J. Mitchell 's Supermarine S.4 and the other Gloster III were damaged before the race and did not compete. Two of the American planes did not finish. Benito Mussolini instructed the Italian aircraft industry to "win the Schneider Trophy at all costs" and so demonstrate

Reportedly half a million spectators lined the beachfronts. The Italian, French, and German entrants failed to ready their aircraft in time for the competition. The remaining British team set both
3760-484: The Italian team won. They were later disqualified and the race was voided, as the referees ruled they had incorrectly flown around a marker buoy. In 1920 and 1921 at Venice the Italians won again; in 1920 no other nation entered and in 1921 the French entry did not start. Had it not been for the 1919 disqualification, Italy would have been awarded the trophy permanently. After 1921, an additional requirement

It was a four-engined floatplane Mercury (the winged messenger) fixed on top of Maia , a heavily modified Short Empire flying boat. The larger Maia took off, carrying the smaller Mercury loaded to a weight greater than it could take off with. This allowed the Mercury to carry sufficient fuel for a direct trans-Atlantic flight with

Meanwhile, Wakefield ordered a floatplane similar to the design of the 1910 Fabre Hydravion. By November 1911, both Gnosspelius and Wakefield had aircraft capable of flight from water and awaited suitable weather conditions. Gnosspelius's flight

After frequent appeals by the industry for subsidies, the Government decided that nationalization was necessary and ordered five aviation companies to merge to form the state-owned Imperial Airways of London (IAL). IAL became the international flag-carrying British airline, providing flying-boat passenger and mail-transport links between Britain and South Africa and India using aircraft such as
4606-424: The company. For two years, the M.C. 72 suffered from many mechanical defects, as well as the loss of two test pilots who died trying to coax world class speed out of the M.C. 72 (first Monti and then Bellini). After 35 flights the engines were overhauled in preparation for a record attempt. The aircraft finally lived up to expectations when it set a new world speed record (over water) on 10 April 1933, with
4700-633: The competition offered a prize of approximately £1,000. The race was held twelve times between 1913 and 1931, the year when it was finally won permanently by the British. It was intended to encourage technical advances in civil aviation but became a contest for pure speed with laps over a (usually) triangular course, initially 280 km (170 mi) and later extended to 350 km (220 mi). The contests were staged as time trials, with aircraft setting off individually at set intervals, usually 15 minutes apart. The contests were very popular, and some of them attracted crowds of over 200,000 spectators. The race

Although France had ordered racing seaplanes from Bernard and Nieuport-Delage in 1928, they were unable to complete them in time for the 1929 race. In 1931 the British government withdrew support, but a private donation of £100,000 from the wealthy and ultra-patriotic Lucy, Lady Houston , allowed Supermarine to compete. When

There was also a tendency for the nose of the aircraft to try to submerge as engine power increased while taxiing on water. This phenomenon had not been encountered before, since Curtiss's earlier designs had not used such powerful engines nor large fuel/cargo loads and so were relatively more buoyant. In order to counteract this effect, Curtiss fitted fins to

The United States, short of funds, did not develop new aircraft for the 1926 title defence; the M.39, designed by Mario Castoldi , used a Fiat AS2 engine and was streamlined in the manner of the 1925 Supermarine and Curtiss entrants. The American teams withdrew from further competition after

After the British finally won permanent possession of the trophy in 1931, the sculpture was displayed for many years at the end of the corridor outside the ballroom of the Lansdowne Club. It has since been entrusted to the Royal Aero Club and can be viewed along with the winning Supermarine S.6B floatplane at the London Science Museum Flight exhibition hall.

In February 1917, the first prototype of the Felixstowe F.3 was flown. It was larger and heavier than the F.2, giving it greater range and heavier bomb load, but poorer agility. Approximately 100 Felixstowe F.3s were produced before the end of the war. The Felixstowe F.5

The German Dornier Do X flying boat was noticeably different from its UK and U.S.-built counterparts. It had wing-like protrusions from the fuselage, called sponsons , to stabilize it on the water without the need for wing-mounted outboard floats. This feature was pioneered by Claudius Dornier during World War I on his Dornier Rs. I giant flying boat and perfected on

If a country won three consecutive races, as the British finally did, they would retain the trophy permanently and the winning pilot would receive 75,000 French francs for each of the first three wins. The races were supervised by the Fédération Aéronautique Internationale and

In November 1939, IAL was restructured into three separate companies: British European Airways , British Overseas Airways Corporation (BOAC), and British South American Airways (which merged with BOAC in 1949), with the change being made official on 1 April 1940. BOAC continued to operate flying-boat services from the (slightly) safer confines of Poole Harbour during wartime, returning to Southampton in 1947. When Italy entered

In 1929, at Calshot , Supermarine won again in the Supermarine S.6 with the new Rolls-Royce R engine with an average speed of 528.89 km/h (328.64 mph). Both Britain and Italy entered two new aircraft and a backup plane from the previous race. Three of the four new aircraft were disqualified (Supermarine S.6 N.248 ) or failed to finish

Seaplanes were sometimes called hydroplanes , but currently this term applies instead to motor-powered watercraft that use the technique of hydrodynamic lift to skim the surface of water when running at speed. The use of seaplanes gradually tapered off after World War II, partially because of

Sir Alan Cobham devised a method of in-flight refuelling in the 1930s. In the air, the Short Empire could be loaded with more fuel than it could take off with. Short Empire flying boats serving the trans-Atlantic crossing were refueled over Foynes; with
6298-594: The new Porte-designed hull, this time fitted with two steps, with the wings of the H-12 and a new tail, and powered by two Rolls-Royce Eagle engines, was named the Felixstowe F.2 and first flew in July 1916, proving greatly superior to the Curtiss on which it was based. It was used as the basis for all future designs. It entered production as the Felixstowe F.2A, being used as a patrol aircraft, with about 100 being completed by
6392-574: The performance, twenty of the modified JRM-1 Mars were ordered. The first, named Hawaii Mars , was delivered in June 1945, but the Navy scaled back their order at the end of World War II, buying only the five aircraft which were then on the production line. The five Mars were completed, and the last delivered in 1947. After World War II, the use of flying boats rapidly declined for several reasons. The ability to land on water became less of an advantage owing to
6486-429: The prize should go to an American aircraft and commissioned the Curtiss Aeroplane and Motor Company to design and build an aircraft capable of making the flight. Curtiss's development of the Flying Fish flying boat in 1913 brought him into contact with John Cyril Porte , a retired Royal Navy Lieutenant, aircraft designer and test pilot who was to become an influential British aviation pioneer. Recognising that many of
6580-534: The race was revived, no longer for seaplanes and under different rules, by the Royal Aero Club of Great Britain to commemorate the 50th anniversary of Britain's ultimate retention of the Schneider Trophy. The original trophy remained in the Science Museum, a full-size replica was cast, and the race opened on a handicapped basis to any propeller–driven landplane capable of maintaining 100 miles per hour (160 km/h; 87 kn) in straight and level flight, and weighing up to 12,500 lb (5,700 kg). Pilots had to have
6674-439: The race. The preparation of the United States team, backed by government support and using Curtiss racing biplanes derived from inter-military competitions, increased the speed and the investment of a winning entry significantly. In 1924 the competition was cancelled as no other nation turned out to face the Americans: the Italians and the French withdrew; and both British craft crashed in pre-race trials. In 1925 at Chesapeake Bay
6768-765: The races until 1991. Since that time, the race has been run by the Royal Aero Club Records Racing and Rally Association along with the King's Cup and the British air racing championship . The venue has varied but is still flown on most occasions around a Solent-based course, usually around September of each year. Seaplane A seaplane is a powered fixed-wing aircraft capable of taking off and landing (alighting) on water. Seaplanes are usually divided into two categories based on their technological characteristics: floatplanes and flying boats ;
6862-452: The remaining as Model H-4s . Four examples of the latter were assembled in the UK by Saunders . All of these were similar to the design of the America and, indeed, were all referred to as America s in Royal Navy service. The engines, however, were changed from the under-powered 160 hp Curtiss engines to 250 hp Rolls-Royce Falcon engines. The initial batch was followed by an order for 50 more (totalling 64 Americas overall during
6956-406: The sides of the bow to add hydrodynamic lift, but soon replaced these with sponsons , a type of underwater pontoon mounted in pairs on either side of a hull. These sponsons (or their engineering equivalents) and the flared, notched hull would remain a prominent feature of flying-boat hull design in the decades to follow. With the problem resolved, preparations for the crossing resumed. While the craft
7050-499: The terminals for many early transatlantic flights. In areas where there were no airfields for land-based aircraft, flying boats could stop at small river, lake or coastal stations to refuel and resupply. The Pan Am Boeing 314 "Clipper" flying boats brought new exotic destinations like the Far East within reach and came to represent the romance of flight. By 1931, mail from Australia was reaching Britain in 16 days, or less than half
7144-452: The time taken by sea. In that year, government tenders on both sides of the world invited applications to run new passenger and mail services between the ends of the Empire, and Qantas and IAL were successful with a joint bid. A company under combined ownership was then formed, Qantas Empire Airways. The new ten-day service between Rose Bay, New South Wales , (near Sydney ) and Southampton
7238-592: The vast distances of the Pacific Theater and Atlantic . They also sank numerous submarines and found enemy ships. In May 1941, the German battleship Bismarck was discovered by a PBY Catalina flying out of Castle Archdale Flying boat base , Lower Lough Erne , Northern Ireland. The largest flying boat of the war was the Blohm & Voss BV 238 , which was also the heaviest plane to fly during World War II and
7332-660: The war in June 1940, the Mediterranean was closed to Allied planes and BOAC and Qantas operated the Horseshoe Route between Durban and Sydney using Short Empire flying boats. The Martin Company produced the prototype XPB2M Mars based on their PBM Mariner patrol bomber, with flight tests between 1941 and 1943. The Mars was converted by the Navy into a transport aircraft designated the XPB2M-1R. Satisfied with
7426-568: The war). Porte also acquired permission to modify and experiment with the Curtiss aircraft. The Curtiss H-4s were soon found to have a number of problems; they were underpowered, their hulls were too weak for sustained operations, and they had poor handling characteristics when afloat or taking off. One flying boat pilot, Major Theodore Douglas Hallam, wrote that they were "comic machines, weighing well under two tons; with two comic engines giving, when they functioned, 180 horsepower; and comic control, being nose heavy with engines on and tail heavy in
7520-536: The world, and the first airline service of any kind at all in the United States. At the same time, the British boat-building firm J. Samuel White of Cowes on the Isle of Wight set up a new aircraft division and produced a flying boat in the United Kingdom. This was displayed at the London Air Show at Olympia in 1913. In that same year, a collaboration between the S. E. Saunders boatyard of East Cowes and
7614-528: Was added: the winning seaplane had to remain moored to a buoy for six hours without human intervention. In 1922 in Naples the British and French competed with the Italians. The British private entry, a Supermarine Sea Lion II , was the victor, flown by Henry Biard . The French aircraft did not start the race, which became a competition between the Sea Lion and three Italian aircraft, two Macchi M.17s and
7708-572: Was attempted by some early flight attempts, but water take off and landing began in earnest in the 1910s and seaplanes pioneered transatlantic routes, and were used in World War I. They continued to develop before World War II, and had widespread use. After World War II, the creation of so many land airstrips meant water landings began to drift into special applications. They continued in niches such as access in remote areas, forest fire fighting, and maritime patrol. The Frenchman Alphonse Pénaud filed
7802-415: Was fitted during hot conditions under the fuselage running from cockpit to tail. The M.C. 72 was built in 1931 for what turned out to be the final Schneider Trophy race, but due to engine problems was unable to compete. Instead of halting development, Macchi continued work on the M.C. 72. Benito Mussolini personally took an interest in seeing development of the M.C. 72 continue and directed state funds to
7896-404: Was found to handle "heavily" on takeoff, and required rather longer take-off distances than expected, the full moon on 5 August 1914 was selected for the trans-Atlantic flight; Porte was to pilot the America with George Hallett as co-pilot and mechanic. Curtiss and Porte's plans were interrupted by the outbreak of World War I. Porte sailed for England on 4 August 1914 and rejoined the Navy as
7990-534: Was intended to combine the good qualities of the F.2 and F.3, with the prototype first flying in May 1918. The prototype showed superior qualities to its predecessors but, to ease production, the production version was modified to make extensive use of components from the F.3, which resulted in lower performance than the F.2A or F.5. Porte's final design at the Seaplane Experimental Station was
8084-468: Was lagging land-based aircraft; seeking to spur amphibious aircraft development, capable of reliable operation, extended range, and reasonable payload capacity, he announced the annual Schneider Trophy competition at a race banquet on 5 December, to cover a distance of at least 150 nautical miles (280 km; 170 mi). The first competition was held on 16 April 1913, at Monaco , consisting of six laps, 300 kilometres (190 mi) distance in total. It
8178-429: Was now on offer, meant that the entry list for the race was large enough to warrant the introduction of heats from 1985 onwards. (There were 62 entrants to the 1984 race, believed at the time to be the largest-ever in all forms of air racing.) The event received further boosts in 1986, when it was started by Prince Andrew, Duke of York and his fiancée Sarah Ferguson; in 1987, when the event was featured as one episode in
8272-456: Was on 13 April 1912. Throughout 1910 and 1911, American pioneering aviator Glenn Curtiss developed his floatplane into the successful Curtiss Model D land-plane, which used a larger central float and sponsons. Combining floats with wheels, he made the first amphibian flights in February 1911 and was awarded the first Collier Trophy for US flight achievement. From 1912, his experiments with
8366-470: Was short-lived, as the aircraft crashed into the lake. Wakefield's pilot, however, taking advantage of a light northerly wind, successfully took off and flew at a height of 50 feet (15 m) to Ferry Nab, where he made a wide turn and returned for a perfect landing on the lake's surface. In Switzerland, Émile Taddéoli equipped the Dufaux 4 biplane with swimmers and successfully took off in 1912. A seaplane
8460-720: Was significant in advancing aeroplane design, particularly in the fields of aerodynamics and engine design, and showed its results in the best fighters of World War II. The streamlined shape and the low drag, liquid-cooled engine pioneered by Schneider Trophy designs are obvious in the British Supermarine Spitfire , the American North American P-51 Mustang , and the Italian Macchi C.202 Folgore . An earlier 1910 trophy for land planes presented by Jacques Schneider, in France,
8554-399: Was such a success that the volume of mail soon exceeded aircraft storage space. A solution was found by the British government, who had requested Short Brothers to design a large long-range monoplane for IAL in 1933. Partner Qantas purchased six Short Empire flying boats. Delivering the mail as quickly as possible generated a lot of competition and some innovative designs. One variant of
8648-645: Was used during the Balkan Wars in 1913, when a Greek "Astra Hydravion" did a reconnaissance of the Turkish fleet and dropped four bombs. In 1913, the Daily Mail newspaper put up a £10,000 prize for the first non-stop aerial crossing of the Atlantic , which was soon "enhanced by a further sum" from the Women's Aerial League of Great Britain . American businessman Rodman Wanamaker became determined that
8742-472: Was well-recognized, and every country bordering on water operated them in a military capacity at the outbreak of the war. They were utilized in various tasks from anti-submarine patrol to air-sea rescue and gunfire spotting for battleships. Aircraft such as the PBM Mariner patrol bomber, PBY Catalina , Short Sunderland , and Grumman Goose recovered downed airmen and operated as scout aircraft over
8836-469: Was won by Maurice Prévost , piloting a French Deperdussin Monocoque (Coupe Schneider) at an average speed of 73.56 km/h (45.71 mph). Although Prévost had averaged a faster flying speed, he lost 50 minutes when he landed prematurely after losing count of the laps completed. All four entrants were flying French-made aircraft; two withdrew before completing the race. The British won in 1914 with
