"The Latécoère 550 was a four-engined French seaplane, designed in the early 1930s as a bomber/torpedo bomber. Though initial handling problems were partly resolved, the aircraft was deemed too slow and did not go into production. Design and development In late 1932 Latécoère received an order from the Commission d'examen des Prototypes et Appareils Nouveaux de l'Aeronautique (CEPANA) for a large four-engined floatplane for bomber and torpedo bomber rôles. The resulting aircraft, the Latécoère 550 flew the following year. It was a high-wing monoplane with its four Gnôme et Rhône 9 Kdr radial engines mounted on the wings in tandem, tractor-pusher pairs. Flight 1 February 1934 p. 107 The tractor motors, neatly cowled, projected well clear of the leading edge; the pusher pair were placed in deep cut-outs in the trailing edge. The cowlings of the latter pair were removed after the first few flights to improve cooling. The wing centre section, between the engines, had an all-metal internal structure and the forward part of the skin was also metal, replaced by fabric further aft. The outer wing sections were slightly tapered on the leading edge only, with elliptical tips; they were entirely fabric-covered over a largely wooden structure, though the principal ribs were metal lattices. 6° of dihedral were added after the first tests. Double ailerons of mixed wood-and-metal construction filled almost all the trailing edges beyond the engine cut-outs. The fuselage was flat-sided and bottomed and only slightly curved on the upper surface. The forward part, from the nose to about midway to the tail was an all-steel structure built on four longerons. Further aft, the longerons continued but were now internally braced with spruce struts and fabric-covered. The forward part was deeper, ending at the rear with an open position for a ventral gunner. At the nose, where the upper fuselage sides curved inwards to an upper gun turret and a navigator's glazed position below, the lower part ended slightly further aft in an enclosure for the bomb aimer. Pilot and co-pilot sat side by side in a glazed cockpit ahead of the leading edge. Behind them, under the same glazing, sat the engineer and the radio operator. Further aft, at the wing trailing edge, was a dorsal gunner's turret. All crew positions were joined by a corridor. The Latécoère 550 had its tailplane mounted on top of the fuselage, strut braced from below and bearing twin inboard fins and rudders separately braced to the top of the fuselage. During flight trials, these vertical surfaces evolved in stages from a rather blunt shape, with extensions below the tailplane to a surface with a smoothly curved trailing edge entirely above the tailplane. The rudders were fitted with trim tabs. Because of the inboard rudders, the elevators had three sections. The 550 was normally equipped with long, single stepped floats. These were mounted below the engines with four vertical spars per side and braced to the fuselage with a further pair running upwards and inwards. Each float also held the inner ends of a pair of lift struts which joined the outer section of the wing at about mid-span. Between engine, float and fuselage the bracing was complicated by further diagonal struts. The floats were replaced for a time with a pair of single wheels, contained in a streamlined structure strong enough to allow attachment of the same struts that connected to the floats. In this landplane configuration a small steerable tailwheel was added. The split undercarriage allowed the 550 to launch torpedoes and bombs from a longitudinally divided bay beneath the fuselage, with a maximum weapons weight of 1,500 kg (3,100 lbs) and torpedoes carried on the port side. The first flight was made from Latécoère's marine base at Biscarosse on 29 April 1933 with the 550 in seaplane form. After some modifications to engine cowlings, wings and tail it went to CEPANA at Saint- Raphaël, Var for trials in October 1933 and in November was converted, in less than four hours, into a landplane. It was not well received and described as unfit for purpose: instabilities, high control loads and pitching on contact with the water were amongst the criticisms. After modifications, including the final vertical stabiliser changes, the 550 went back to CEPANA in April 1934 in seaplane form. It seems to have handled better, but by now its maximum speed was seen as low; when the sole 550 was lost in October 1934, its port float struts collapsing on alighting, there was no enthusiasm for further development.

"Peter Betham (born 6 January 1989) is a professional rugby union player. He currently plays for the Clermont Auvergne in the Top 14. He was a representative player for Australia in international rugby matches. His usual position is wing or fullback. Family and early career Betham was born in Wellington, New Zealand to parents of Samoan heritage. His family moved to Australia and he was brought up in Sydney where he started playing rugby league with the Coogee Randwick Wombats club at the age of 10. He played high school rugby for St. Joseph's College, Hunters Hill located on Sydney's Lower North Shore. He became friends with St. Joseph's teammate Kurtley Beale and for two years the pair backed up with Kensington in the South Sydney junior rugby league competition. Having attended a public primary school, Peter represented Sydney East PSSA at the State Championships in 2001 at Kiama. His teammate Rob Horne and Peter went on to represent NSW PSSA that year. Betham played for NSW Schools in the 2005 National U16 Championship. He subsequently played for the Australia A Schools team that went on to beat New Zealand. In 2006 Betham toured Fiji and New Zealand with the Australian Schoolboys team. In 2007 he played rugby while studying American history at Sydney University, and was selected in the Australian U19 Rugby World Championship squad. He also became a holder of an Australian Institute of Sport (AIS) scholarship, one of 26. Rugby union career Betham played for the Brumbies in the Super 14 competition, but injuries kept him off the field until mid 2009 when he rejoined Sydney University where he helped the club win the Sydney competition that year. In 2010 he continued to play for Sydney Uni, and trained with the Waratahs' squad, as an "unsigned winger" and played in several Tahs' pre- season games. In March 2010 Betham signed with the Melbourne Rebels for the 2011 Super Rugby season, with Rebels assistant coach Damian Hill describing him as "one of the most dynamic and athletic young backs" in Australian rugby. He spent 2011 in Victoria before returning to NSW. In February 2012 Betham was named to play on the wing in the Tahs' pre-season match against Tonga. In April 2015 Betham signed for Leicester Tigers. He will join them after the 2015 Super Rugby season finishes mid-2015. Betham marked his Tigers' debut with a try in their opening win of the season over London Irish in October 2015. The tigers have used Betham in both the outside centre role and on the wing. In January 2017 Betham signed a new contract to stay at the club. In May 2017 Betham signed a contract with Clermont Auvergne for two years.
