BRITISH JET AIRLINER PLANNED FOR FLIGHT TO AUSTRALIA

Great Britain's now fleet of civil airliners is now going through the last phases of testing before setting out on demonstrations and proving flights overscas, Preparations for putting the new aeroplanes into production and service on the international oir routes have made rapid strides since last September, when the air show at Farnborough, organised by the Society of British Aircraft Constructors, proved to the world that Great Britoin had taken the lead in jet and turbo- prop civil aircraft.

Although the British Electricity Authority has at present standardised on 30 MW and 60 MW sots for its present programme, futuro requirements are likely to call for sets up to 100 MW, and the new building: will place the Company in a position to meet all demands for such plant.
