A flying boat is a fixed - winged seaplane with a hull , allowing it to land on water , that usually has no type of landing gear to allow operation on land . It differs from a floatplane as it uses a purpose - designed fuselage which can float , granting the aircraft buoyancy . Flying boats may be stabilized by under - wing floats or by wing - like projections ( called sponsons ) from the fuselage . Flying boats were some of the largest aircraft of the first half of the 20th century , exceeded in size only by bombers developed during World ___MASK26___ II . Their advantage lay in using water instead of expensive land - based runways , making them the basis for international airlines in the interwar period . They were also commonly used for maritime patrol and air - sea rescue . In the context of the ___MASK86___ of the 20th century , the interwar period or " interbellum " ( Latin : " inter -", " between " + " bellum ", " ___MASK26___ ") was the period between the end of the First World ___MASK26___ ( 1914  18 ) and the beginning of the Second World ___MASK26___ ( 1939  45 ) the period beginning with the Armistice of 11 November 1918 that concluded the First World ___MASK26___ and the ensuing Paris Peace Conference in 1919 , and ending in September 1939 with the German invasion of Poland and the start of the World ___MASK26___ II .

Non - Stop New York ( aka Libson Clipper Mystery ) is a 1937 British ___MASK74___ ___MASK81___ and science fiction ___MASK81___ directed by Robert Stevenson and starring John Loder , Anna Lee and ___MASK82___ L . Sullivan . It is based on the novel Sky Steward by Ken Attiwill . A woman who can clear an innocent man of the charge of murder is pursued by gangsters onto a luxurious transatlantic flying boat . ___MASK82___ Loftus Sullivan ( 6 January 1903  19 November 1956 ) was an English film and stage actor . In ordinary ___MASK24___ , a ___MASK74___ is an unlawful act punishable by a state or other authority . The term " ___MASK74___ " does not , in modern criminal ___MASK35___ , have any simple and universally accepted definition , though statutory definitions have been provided for certain purposes . The most popular view is that ___MASK74___ is a category created by ___MASK35___ ; in other words , something is a ___MASK74___ if declared as such by the relevant and applicable ___MASK35___ . One proposed definition is that a ___MASK74___ or offence ( or criminal offence ) is an act harmful not only to some individual or individuals but also to a community , society or the state (" a public wrong "). Such acts are forbidden and punishable by ___MASK35___ . In ___MASK56___ , buoyancy ( or ; also known as upthrust ) is an upward force exerted by a fluid that opposes the weight of an immersed object . In a column of fluid , pressure increases with depth as a result of the weight of the overlying fluid . Thus the pressure at the bottom of a column of fluid is greater than at the top of the column . Similarly , the pressure at the bottom of an object submerged in a fluid is greater than at the top of the object . This pressure difference results in a net upwards force on the object . The magnitude of that force exerted is proportional to that pressure difference , and ( as explained by Archimedes ' principle ) is equivalent to the weight of the fluid that would otherwise occupy the volume of the object , i . e . the displaced fluid . ___MASK74___ films are a genre of ___MASK81___ that focus on crime . The stylistic approach to a crime ___MASK81___ varies from realistic portrayals of real - life criminal figures , to the far - fetched evil doings of imaginary arch - villains . An airline is a ___MASK33___ that provides air transport services for traveling passengers and freight . Airlines utilize aircraft to supply these services and may form partnerships or alliances with other airlines for codeshare agreements . Generally , airline companies are recognized with an air operating certificate or license issued by a governmental ___MASK97___ body . A seaplane is a powered fixed - wing aircraft capable of taking off and landing ( alighting ) on water . Seaplanes that can also take off and land on airfields are in a subclass called " amphibious aircraft ". Seaplanes and amphibians are usually divided into two categories based on their technological characteristics : floatplanes and flying boats ; the latter are generally far larger and can carry far more . These aircraft 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 ___MASK67___ at speed .
