NO technical development in all our industrial history has been as highly glamorized as the subject of plastics. It has shown an amazing degree of popular appeal for several reasons, including probably the idea of synthesis from coal, air and water, the beauty of colour and finish in decorative effects, and the fact that the objects of early manufacture were those of common use by the general public. Feature writers have regrctably enjoyed a general fieldday revelling in the subject, and unfortunately there has been a tendency towards certain misconceptions and exaggerations in such writings. Plastic aeroplanes now flying, plastic automobiles and plastic homes of the future have been described. Actually there is no such thing today as the plastic aeroplane. The plywood airframe has attained great importance owing to the advent of plastic glues, and what might be termed a plywood plastic aircraft is still actually a highgrade plywood. The plastic automobile bodies envisaged today are secondary structures to be built over a metal framework. The postwar homes will undoubtedly have dozens of items in which plastics will play a part, but primary loadcarrying structures are not among these components as yet. The plastic industry itself has recently become somewhat concerned about the dangers attendant on overglamorization and some remedial action has been studied.
