O'Neill and D.C. Eyre During 1933 the well known Australian aviator. Sir Charles Kingsford Smith, made preparations to fly his Fokker F.VIIb.3m VH—USD "Southern Cross" to New Zealand to make a 'passenger carrying tour' (which was probably a barnstorming tour of the islands) accompanied by a'machine' which had been designed to his specifications by Wing Commander L.J. Wackett!' ^ This 'machine' had been named the Codock (an abbreviation of Cockatoo Dockyard) and was built by the Cockatoo Island Dockyard in Sydney, a most unlikely place to build an aircraft if there ever was one. The appellation L.J.W.6 was also given to the Codock, L.J.W. being the designers initials and the figure 6_ indicating it was his sixth design. The pilot of the Codock on the tour of New Zealand was to be the well known New Zealand aviator. Squadron Leader T.W. 'Tiny' White. Preparations for the construction of the twin-engined monoplane for Sir Charles Kingsford Smith were com pleted by Wing Commander Wackett at Cockatoo Island Dockyard in about July 1933 and it was hoped to commence con struction during August. The design of the Codock was a redesign of a similar aircraft (unnamed and unbuilt) which had been designed by Wackett prior to his receiving the specifications from Kingsford Smith for the Codock, and which had been designed with the hope of sale in reasonable numbers on the Australian market. Planning was still in the initial stages when Kingsford Smith requested the design of the Codock and so the initial plans were dropped in favour of a design to meet the new specifications. Initial design studies developed around the installation of the proven de Havilland Gipsy (probably IV) engine but when the Napier Javelin engine became available, it was decided that this should be the definitive power plant and modi fications were made to the design in order that these engines (of higher power than the Gipsy) could be fitted, thus allowing the designers to make an all-round increase in the size of the aircraft and giving it a greater load carrying capacity and per formance. The contract price to Kingsford Smith for the Codock was for £3,700 ($7,400) with engines fitted and ready to fly at Mascot aerodrome. New South Wales. Along with the proposed tour to New Zealand, which was probably to be a fund raising type venture to set up his company reasonably well financially, Kingsford Smith had also tendered to the Austra lian Government for rights to the Australia — Singapore link in the Royal Mail service from England to Australia, the tender stating that the Codock would be the aircraft to service the route. An important feature of the design, and a proposed strong selling point for future production aircraft, was its ability to maintain a height of 5,000 ft. on one engine, thus it "possessed the reliability and safety of a multi-engined passenger aircraft." The building of the first aircraft (c/n 1 — the only Codock built) was not as smooth as it might have been. The magazine "Aircraft" for May 1934 reported: "Few persons — other than those who have sweated and suffered — realise the multitude of snags and delays which can interfere with the design, construction, test flights, airworthiness trials, and the final handing over as a commercial proposition, of a prototype aeroplane built in a factory without the advantage of previous construction of complete aircraft. Add to that a series of delays in obtaining delivery of engines, which are themselves just coming forward on a production basis, and you have cause for a real headache............ Most of the overseas makers are able to conduct the initial breaking-in period of flying on their own private aerodromes. In Australia, however, the birth of a new type is unfortunately so rare that the 'What-did-l-tell-you?' brigade has ample opportunity to make premature criticism and to deride the work of fellow Australians." By the beginning of March 1934 the Codock was completed and on the 6th it made its initial test flight at the hands of Kingsford Smith at Mascot. He reported that it had taken off well, but that fore and aft controls were heavy. Modifications were made and following a further flight the following day, he was reported to be "obviously satisfied." After preliminary testing, slight modifications were made to the carburettor jets and the aircrafts control system. During these tests, Sqdn Ldr White (the pilot for the proposed Tasman crossing already referred to) did a considerable amount of test flying with a number of specialists in the cabin in readiness for the official trials essential to the granting of a type Certificate of Airworthiness. His crew included: H. Purvis (engineer); S.V. Colville (designer and maker of the radio equipment installed); and H. Foster (Navigator and radio operator from New Zealand). At about this time plans were in train for a further Codock to be built to order for the Air Board but this did not eventuate and in fact the first production example of the Codock's successor, the Tugan Gannet, was purchased by the Air Board for the R.A.A.F. On April 10, 1934, Sqdn Ldr White flew the Codock to Essendon Aerodrome, Victoria, and whilst in that State a number of country districts were visited, including Wilson's Promontory, Warrnambool, Ballarat and Echuca. The idea was to run the engines in and allow the crew for the proposed trans-Tasman flight time to acquaint themselves with the behaviour of their equipment in varied weather conditions and with a range of "all-up" weights.
