63-533: The Schlesinger Race , also known as the "Rand Race" , the "Portsmouth – Johannesburg Race" or more commonly the 'African Air Race', took place in September 1936. The Royal Aero Club announced the race on behalf of Isidore William Schlesinger who wanted to promote the Empire Exhibition, South Africa and so offered a total of £10,000 in prize money to be divided into two sections, a speed race and
126-572: A forced crash landing 150 miles south of Salisbury in his Miles Hawk Six . In 1937 Charles E. Gardner went on to win the King's Cup Race in the repaired Mew Gull G-AEKL in which Black had suffered his fatal accident. Guthrie also flew in this race in Vega Gull G-AFAU, finishing in fifth place. Due to the fact that only one entrant finished the race, Schlesinger suggested that the finishers money which would remain unclaimed should be paid to
189-587: A forced landing 20 miles before Salisbury . D. Llewellyn and C. Hughesdon in Percival Vega Gull had a forced landing before Abercorn (today's Mbala ), on a shore of Lake Tanganika . In a difficult weather conditions, the Airspeed Envoy crashed during a take off from Abercorn, killing the pilot Maxwell Findlay and radio operator A. Morgan, while Kenneth Waller and the passenger Derek Peachey escaped with injuries. Finally, A.E. Clouston made
252-604: A forced landing near Regensburg in Germany and damaged an undercarriage. A. Miller, flying Percival Mew Gull , had a forced landing before Belgrade and withdrew. Next, T. Rose's B.A.4 Double Eagle got damaged on an airfield in Cairo, due to undercarriage folding. Victor Smith flying Miles Sparrowhawk had problems with oil since Salonika and eventually retired in Khartoum. On 30 September, S. Halse crashed his Percival Mew Gull in
315-533: A genus level, six species of Chrysichthys catfish are only found in the Tanganyika basin where they live both in shallow and relatively deep waters; in the latter habitat they are the primary predators and scavengers. A unique evolutionary radiation in the lake is the 15 species of Mastacembelus spiny eels, all but one endemic to its basin. Although other African Great Lakes have Synodontis catfish, endemic catfish genera and Mastacembelus spiny eels,
378-586: A handicap race. The two sections were to be flown concurrently, but no competitor could win both first prizes. The race was wholly inspired by the very successful 1934 MacRobertson Air Race to celebrate the centenary of the Australian state of Victoria. However, whilst that race was open to all-comers, Schlesinger made the fundamental error of restricting the entry of the Schlesinger Race to British Empire crews and machines only. This led directly to
441-429: A much smaller entry and only one machine successfully completed the course after many aircraft either failed, crashed or given up. Magazines of the time, such as The Aeroplane and Flight , were suitably scathing. MacRobertson Air Race winner C.W.A. Scott aided by Giles Guthrie won the race in a Percival Vega Gull, but it was a hollow victory, as most of the waiting spectators at Cape Town had given up and gone home by
504-632: A photograph was taken outside Mussell Manor of the Wright Brothers with all of the early British aviation pioneers to commemorate their visit to Britain. In October 1909, the club recognised the Blackpool Aviation Week , making it Britain's first official air show . On 30 October Moore-Brabazon was also the first to cover a mile (closed circuit) in a British aeroplane, flying the Short Biplane No. 2 , and so winning
567-637: A prize of £1,000 offered by the Daily Mail newspaper. On 4 November 1909, he decided to take up a piglet, which he named Icarus the Second, as a passenger, thereby disproving the adage that "pigs can't fly". It moved the next year to nearby Eastchurch , where the Royal Navy had established a flying school. Until 1911 the British Military did not have any pilot training facilities. As
630-646: A result, most early military pilots were trained by members of the club and many became members. By the end of the First World War, more than 6,300 military pilots had taken RAeC Aviator's Certificates. After the loss of its Piccadilly clubhouse in 1961, the club was lodged at the Lansdowne Club at 9 Fitzmaurice Place until 1968. It then moved for a short spell to the Junior Carlton Club 's modern building at 94 Pall Mall . In June 1973

It had a clubhouse at 119 Piccadilly , which it retained until 1961. The club was granted its Royal prefix on 15 February 1910. From 1910 the club issued Aviators Certificates, which were internationally recognised under the Fédération Aéronautique Internationale (the FAI) to which
819-488: A threatened subspecies of banded water cobra that feeds mainly on fish, is only found in Lake Tanganyika, where it prefers rocky shores. Lake Tanganyika is home to at least 250 endemic species of cichlids , and undescribed species likely remain to be discovered. Almost all (roughly 98%) of the lake's cichlid species are found solely there, and nowhere else, thus making it a precious biological resource for
882-532: A turbulently volcanic area that has undergone climate changes. Apparently, it has rarely in the past had an outflow to the sea. It has been described as "practically endorheic " for this reason. The lake's connection to the sea is dependent on a high water level allowing water to overflow out of the lake through the Lukuga River into the Congo. When not overflowing, the lake's exit into the Lukuga River typically
945-446: Is an ancient lake , one of only twenty more than a million years old. Its three basins, which in periods with much lower water levels were separate lakes, are of different ages. The central began to form 9–12 million years ago (Mya), the northern 7–8 Mya and the southern 2–4 Mya. The lake's water is alkaline with a pH around 9 at depths of 0–100 m (0–330 ft). Below this, it is around 8.7, gradually decreasing to 8.3–8.5 in
1008-521: Is blocked by sand bars and masses of weed, and instead this river depends on its own tributaries, especially the Niemba River, to maintain a flow. The lake may also have at times had different inflows and outflows; inward flows from a higher Lake Rukwa , access to Lake Malawi and an exit route to the Nile have all been proposed to have existed at some point in the lake's history. Lake Tanganyika
1071-424: Is deeper than any other cichlid known. Some of the deepwater genera (e.g., Bathybates , Gnathochromis , Hemibates and Xenochromis ) have been caught in places virtually devoid of oxygen, and how they are able to survive there is unclear. Tanganyika cichlids are generally benthic (found at or near the bottom) and/or coastally. No Tanganyika cichlids are truly pelagic and offshore, except for some of
1134-488: Is far more stable and consistent than the rapids and fast-flowing sections of the Congo River. Additionally, Lake Tanganyika's water is alkaline and of a higher pH (which the cichlids prefer), containing a higher calcium and mineral content than the Congo's acidic , sediment -rich waters, which collect much organic detritus from the surrounding rainforests . In areas of the Congo away from rapids or whitewater ,
1197-461: Is home to more than 80 species of non-cichlid fish and about 60% of these are endemic. The open waters of the pelagic zone are dominated by four non-cichlid species: Two species of "Tanganyika sardine" ( Limnothrissa miodon and Stolothrissa tanganicae ) form the largest biomass of fish in this zone, and they are important prey for the forktail lates ( Lates microlepis ) and sleek lates ( L. stappersii ). Two additional lates are found in

It drains into the Congo River system and ultimately into the Atlantic Ocean . Lake Tanganyika is situated within the Albertine Rift , the western branch of the East African Rift , and is confined by
1323-482: Is unclear if they have a similar behavior. The facultative brood parasites often lay their eggs synchronously with mouthbroding cichlids. The cichlid pick up the eggs in their mouth as if they were their own. Once the catfish eggs hatch the young eat the cichlid eggs. Six catfish genera are entirely restricted to the lake basin: Bathybagrus , Dinotopterus , Lophiobagrus , Phyllonemus , Pseudotanganikallabes and Tanganikallabes . Although not endemic on

Among Rift Valley lakes , Lake Tanganyika far surpasses all others in terms of crustacean and freshwater snail richness (both in total number of species and number of endemics). For example,
1449-713: The piscivorous Bathybates . Two of these, B. fasciatus and B. leo , mainly feed on Tanganyika sardines . Tanganyika cichlids differ extensively in ecology , and include species that are herbivores , detritivores , planktivores , insectivores , molluscivores , scavengers , scale-eaters and piscivores. These dietary specializations, however, have been shown to be variable and subject to opportunistic changes. That is, many species of Tanganyikan cichlid with specialized diets showed opportunistic, episodic exploitation of Stolothrissa tanganicae and Limnothrissa miodon when prey concentrations were unusually high. The fishes' breeding behavior falls into two main groups:

A number of air races were organised by the club: The Britannia Trophy is presented by the Royal Aero Club for aviators accomplishing the most meritorious performance in aviation during
1701-450: The Tanganyika thalassoids, which are part of Prosobranchia , are endemic to the lake. Initially they were believed to be related to similar marine snails, but they are now known to be unrelated. Their appearance is now believed to be the result of the highly diverse habitats in Lake Tanganyika and evolutionary pressure from snail-eating fish and, in particular, Platythelphusa crabs. A total of 17 freshwater snail genera are endemic to
1764-552: The accumulated sediment and organic matter creates sections of " blackwater ", with a high concentration of tannins from dissolving wood and leaves, creating an environment in which cichlids simply do not thrive. Likewise, many tropical riverine species would likely suffer if exposed to the crisp, alkaline lake water. Although Lake Tanganyika has fewer cichlid species than Lakes Malawi or Victoria —which both have experienced relatively recent explosive species radiations (resulting in many closely related species)—, its cichlids are

One called Lusenga which is a wide net used by one person from a canoe. The second one is using a lift net. This was done by dropping a net deep below the boat using two parallel canoes and then simultaneously pulling it up. The third is called Chiromila which consisted of three canoes. One canoe
1890-723: The club merged with the United Service Club and moved into its premises at 116 Pall Mall. All its aviation-related activities were then transferred to the Aviation Council (United Service and Royal Aero Club) Ltd incorporated on 15 February 1973. In June 1975, the United Service and Royal Aero Club merged with the Naval and Military Club and on 1 August 1975 the Royal Aero Club of the United Kingdom
1953-557: The club was the UK representative. The club is the governing body in the UK for air sports, as well as for records and competitions. The club established its first flying ground on a stretch of marshland at Shellbeach near Leysdown on the Isle of Sheppey in early 1909. A nearby farmhouse, Mussell Manor (now called Muswell Manor) became the flying ground clubhouse, and club members could construct their own sheds to accommodate their aircraft. Among

This is officially recognised as the first flight by a British pilot in Britain. The same week the Wright brothers visited the Aero Club flying ground at Shellbeach. After inspecting the Short Brothers' factory,

Two of the brothers, Eustace and Oswald , had previously made balloons for Aero Club members and been appointed the official engineers of the Aero Club. They had also enlisted their eldest brother, Horace, when they decided to begin constructing heavier-than-air aircraft. They acquired a licence to build copies of the Wright aircraft and set up

It is thought that early Homo sapiens were making an impact on the region during the Stone Age . The time period of the Middle Stone Age to Late Stone Age is described as an age of advanced hunter-gatherers. There are many methods in which the native people of
2331-482: The genera Altolamprologus , Cyprichromis , Eretmodus , Julidochromis , Lamprologus , Neolamprologus , Tropheus and Xenotilapia , are popular aquarium fish due to their bright colors and patterns, and interesting behaviors. Recreating a Lake Tanganyika biotope to host those cichlids in a habitat similar to their natural environment is also popular in the aquarium hobby, with many species today being bred in captivity successfully. Lake Tanganyika

Others have proposed splitting the Tanganyika cichlids into as many as 12–16 tribes ( Bathybatini , Benthochromini , Boulengerochromini , Cyphotilapiini , Eretmodini , Greenwoodochromini , Perissodini and Trematocarini , in addition to the aforementioned tribes). Most Tanganyika cichlids live along the shoreline, down to a depth of 100 m (330 ft), but some deep-water species regularly descend to 200 m (660 ft). Trematocara species have, exceptionally, been found at more than 300 m (980 ft), which

Under the command of Lieutenant Commander Geoffrey Spicer-Simson the British Royal Navy achieved the monumental task of bringing two armed motor boats HMS Mimi and HMS Toutou from England to the lake by rail, road and river to Albertville (since renamed Kalemie in 1971) on
2520-936: The lake, such as Hirthia , Lavigeria , Paramelania , Reymondia , Spekia , Stanleya , Tanganyicia and Tiphobia . There are about 30 species of non-thalassoid snails in the lake, but only five of these are endemic, including Ferrissia tanganyicensis and Neothauma tanganyicense . The latter is the largest Tanganyika snail and its shell is often used by small shell-dwelling cichlids . Crustaceans are also highly diverse in Tanganyika with more than 200 species, of which more than half are endemic. They include 10 species of freshwater crabs (9 Platythelphusa and Potamonautes platynotus ; all endemic), at least 11 species of small atyid shrimp ( Atyella , Caridella and Limnocaridina ), an endemic palaemonid shrimp ( Macrobrachium moorei ), about 100 ostracods , including many endemics, and several copepods . Among these, Limnocaridina iridinae lives inside

The four lates, all endemic to Tanganyika, have been overfished and larger individuals are rare today. Among the more unusual fish in the lake are the endemic, facultatively brood parasitic "cuckoo catfish", including at least Synodontis grandiops and S. multipunctatus . A number of others are very similar (e.g., S. lucipinnis and S. petricola ) and have often been confused; it

Many of the snails are unusual for species living in freshwater in having noticeably thickened shells and/or distinct sculpture , features more commonly seen in marine snails. They are referred to as thalassoids, which can be translated to "marine-like". All
2709-431: The lake. As a consequence of the stratification, the deep sections contain " fossil water ". This also means it has no oxygen (it is anoxic ) in the deeper parts, essentially limiting fish and other aerobic organisms to the upper part. Some geographical variations are seen in this limit, but it is typically at depths around 100 m (330 ft) in the northern part of the lake and 240–250 m (790–820 ft) in

Tanganyika has the largest number of endemic cichlid genera of all African lakes. All Tanganyika cichlids are in the subfamily Pseudocrenilabrinae . Of the 10 tribes in this subfamily, half are largely or entirely restricted to the lake ( Cyprichromini , Ectodini , Lamprologini , Limnochromini and Tropheini ), while another three have species in

The Malagarasi is older than Lake Tanganyika, and before the lake was formed, it probably was a headwater of the Lualaba River , the main Congo River headstream. The lake has a complex history of changing flow patterns, due to its high altitude, great depth, slow rate of refill, and mountainous location in
3024-418: The only other Rift Valley lake with endemic freshwater crabs are Lake Kivu and Lake Victoria with two species each. The diversity of other invertebrate groups in Lake Tanganyika is often not well-known, but there are at least 20 described species of leeches (12 endemics), 9 sponges (7 endemic), 6 bryozoa (2 endemic), 11 flatworms (7 endemic), 20 nematodes (7 endemic), 28 annelids (17 endemic) and
